- * Interface for an element's attribute specifications.
- *
- * <blockquote>
- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p>This is the original SAX1 interface for reporting an element's
- * attributes.  Unlike the new {@link org.xml.sax.Attributes Attributes}
- * interface, it does not support Namespace-related information.</p>
- *
- * <p>When an attribute list is supplied as part of a
- * {@link org.xml.sax.DocumentHandler#startElement startElement}
- * event, the list will return valid results only during the
- * scope of the event; once the event handler returns control
- * to the parser, the attribute list is invalid.  To save a
- * persistent copy of the attribute list, use the SAX1
- * {@link org.xml.sax.helpers.AttributeListImpl AttributeListImpl}
- * helper class.</p>
- *
- * <p>An attribute list includes only attributes that have been
- * specified or defaulted: #IMPLIED attributes will not be included.</p>
- *
- * <p>There are two ways for the SAX application to obtain information
- * from the AttributeList.  First, it can iterate through the entire
- * list:</p>
- *
- * <pre>
- * public void startElement (String name, AttributeList atts) {
- *   for (int i = 0; i < atts.getLength(); i++) {
- *     String name = atts.getName(i);
- *     String type = atts.getType(i);
- *     String value = atts.getValue(i);
- *     [...]
- *   }
- * }
- * </pre>
- *
- * <p>(Note that the result of getLength() will be zero if there
- * are no attributes.)
- *
- * <p>As an alternative, the application can request the value or
- * type of specific attributes:</p>
- *
- * <pre>
- * public void startElement (String name, AttributeList atts) {
- *   String identifier = atts.getValue("id");
- *   String label = atts.getValue("label");
- *   [...]
- * }
- * </pre>
- *
- * @deprecated This interface has been replaced by the SAX2
- *             {@link org.xml.sax.Attributes Attributes}
- *             interface, which includes Namespace support.
- * @since SAX 1.0

+ * </blockquote>
+ *
+ * <p>This interface allows access to a list of attributes in
+ * three different ways:</p>
+ *
+ * <ol>
+ * <li>by attribute index;</li>
+ * <li>by Namespace-qualified name; or</li>
+ * <li>by qualified (prefixed) name.</li>
+ * </ol>
+ *
+ * <p>The list will not contain attributes that were declared
+ * #IMPLIED but not specified in the start tag.  It will also not
+ * contain attributes used as Namespace declarations (xmlns*) unless
+ * the <code>http://xml.org/sax/features/namespace-prefixes</code> 
+ * feature is set to <var>true</var> (it is <var>false</var> by 
+ * default).
+ * Because SAX2 conforms to the "Namespaces in XML" specification,
+ * it does not give namespace declaration attributes a namespace URI.
+ * Some other W3C specifications are in conflict with that, expecting
+ * these declarations to be in a namespace.
+ * Handler code may need to resolve that conflict.
+ * </p>
+ *
+ * <p>If the namespace-prefixes feature (see above) is <var>false</var>, 
+ * access by qualified name may not be available; if the 
+ * <code>http://xml.org/sax/features/namespaces</code>
+ * feature is <var>false</var>, access by Namespace-qualified names 
+ * may not be available.</p>
+ *
+ * <p>This interface replaces the now-deprecated SAX1 {@link
+ * org.xml.sax.AttributeList AttributeList} interface, which does not 
+ * contain Namespace support.  In addition to Namespace support, it 
+ * adds the <var>getIndex</var> methods (below).</p>

- * Receive notification of the logical content of a document.

- * <blockquote>
- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p>This is the main interface that most SAX applications
- * implement: if the application needs to be informed of basic parsing 
- * events, it implements this interface and registers an instance with 
- * the SAX parser using the {@link org.xml.sax.XMLReader#setContentHandler 
- * setContentHandler} method.  The parser uses the instance to report 
- * basic document-related events like the start and end of elements 
- * and character data.</p>
- *
- * <p>The order of events in this interface is very important, and
- * mirrors the order of information in the document itself.  For
- * example, all of an element's content (character data, processing
- * instructions, and/or subelements) will appear, in order, between
- * the startElement event and the corresponding endElement event.</p>
- *
- * <p>This interface is similar to the now-deprecated SAX 1.0
- * DocumentHandler interface, but it adds support for Namespaces
- * and for reporting skipped entities (in non-validating XML
- * processors).</p>
- *
- * <p>Implementors should note that there is also a Java class
- * {@link java.net.ContentHandler ContentHandler} in the java.net
- * package; that means that it's probably a bad idea to do</p>
- *
- * <blockquote>
- * import java.net.*;
- * import org.xml.sax.*;
- * </blockquote>
- *
- * <p>In fact, "import ...*" is usually a sign of sloppy programming
- * anyway, so the user should consider this a feature rather than a
- * bug.</p>

+ * <p>This is the main interface that most SAX applications
+ * implement: if the application needs to be informed of basic parsing 
+ * events, it implements this interface and registers an instance with 
+ * the SAX parser using the {@link org.xml.sax.XMLReader#setContentHandler 
+ * setContentHandler} method.  The parser uses the instance to report 
+ * basic document-related events like the start and end of elements 
+ * and character data.</p>
+ *
+ * <p>The order of events in this interface is very important, and
+ * mirrors the order of information in the document itself.  For
+ * example, all of an element's content (character data, processing
+ * instructions, and/or subelements) will appear, in order, between
+ * the startElement event and the corresponding endElement event.</p>
+ *
+ * <p>This interface is similar to the now-deprecated SAX 1.0
+ * DocumentHandler interface, but it adds support for Namespaces
+ * and for reporting skipped entities (in non-validating XML
+ * processors).</p>
+ *
+ * <p>Implementors should note that there is also a Java class
+ * {@link java.net.ContentHandler ContentHandler} in the java.net
+ * package; that means that it's probably a bad idea to do</p>
+ *
+ * <blockquote>
+ * import java.net.*;
+ * import org.xml.sax.*;

+ *
+ * <p>The order of events in this interface is very important, and

+ * example, all of an element's content (character data, processing
+ * instructions, and/or subelements) will appear, in order, between
+ * the startElement event and the corresponding endElement event.</p>
+ *
+ * <p>Application writers who do not want to implement the entire

+ * the default functionality; parser writers can instantiate
+ * HandlerBase to obtain a default handler.  The application can find
+ * the location of any document event using the Locator interface
+ * supplied by the Parser through the setDocumentLocator method.</p>

+ *             {@link org.xml.sax.ContentHandler ContentHandler}
+ *             interface, which includes Namespace support.

-/**
- * A single input source for an XML entity.
- *
- * <blockquote>
- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p>This class allows a SAX application to encapsulate information
- * about an input source in a single object, which may include
- * a public identifier, a system identifier, a byte stream (possibly
- * with a specified encoding), and/or a character stream.</p>
- *
- * <p>There are two places that the application will deliver this
- * input source to the parser: as the argument to the Parser.parse
- * method, or as the return value of the EntityResolver.resolveEntity
- * method.</p>
- *
- * <p>The SAX parser will use the InputSource object to determine how
- * to read XML input.  If there is a character stream available, the
- * parser will read that stream directly; if not, the parser will use
- * a byte stream, if available; if neither a character stream nor a
- * byte stream is available, the parser will attempt to open a URI
- * connection to the resource identified by the system
- * identifier.</p>
- *
- * <p>An InputSource object belongs to the application: the SAX parser
- * shall never modify it in any way (it may modify a copy if 
- * necessary).</p>

+ *
+ * <p>This class allows a SAX application to encapsulate information
+ * about an input source in a single object, which may include
+ * a public identifier, a system identifier, a byte stream (possibly
+ * with a specified encoding), and/or a character stream.</p>
+ *
+ * <p>There are two places that the application can deliver an
+ * input source to the parser: as the argument to the Parser.parse
+ * method, or as the return value of the EntityResolver.resolveEntity
+ * method.</p>
+ *
+ * <p>The SAX parser will use the InputSource object to determine how
+ * to read XML input.  If there is a character stream available, the
+ * parser will read that stream directly, disregarding any text
+ * encoding declaration found in that stream.
+ * If there is no character stream, but there is
+ * a byte stream, the parser will use that byte stream, using the
+ * encoding specified in the InputSource or else (if no encoding is
+ * specified) autodetecting the character encoding using an algorithm
+ * such as the one in the XML specification.  If neither a character
+ * stream nor a
+ * byte stream is available, the parser will attempt to open a URI
+ * connection to the resource identified by the system
+ * identifier.</p>
+ *
+ * <p>An InputSource object belongs to the application: the SAX parser
+ * shall never modify it in any way (it may modify a copy if 
+ * necessary).  However, standard processing of both byte and
+ * character streams is to close them on as part of end-of-parse cleanup,
+ * so applications should not attempt to re-use such streams after they
+ * have been handed to a parser.  </p>

- * Interface for reading an XML document using callbacks.

- * <blockquote>
- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p><strong>Note:</strong> despite its name, this interface does 
- * <em>not</em> extend the standard Java {@link java.io.Reader Reader} 
- * interface, because reading XML is a fundamentally different activity 
- * than reading character data.</p>
- *
- * <p>XMLReader is the interface that an XML parser's SAX2 driver must
- * implement.  This interface allows an application to set and
- * query features and properties in the parser, to register
- * event handlers for document processing, and to initiate
- * a document parse.</p>
- *
- * <p>All SAX interfaces are assumed to be synchronous: the
- * {@link #parse parse} methods must not return until parsing
- * is complete, and readers must wait for an event-handler callback
- * to return before reporting the next event.</p>
- *
- * <p>This interface replaces the (now deprecated) SAX 1.0 {@link
- * org.xml.sax.Parser Parser} interface.  The XMLReader interface
- * contains two important enhancements over the old Parser
- * interface:</p>
- *
- * <ol>
- * <li>it adds a standard way to query and set features and 
- *  properties; and</li>
- * <li>it adds Namespace support, which is required for many
- *  higher-level XML standards.</li>
- * </ol>
- *
- * <p>There are adapters available to convert a SAX1 Parser to
- * a SAX2 XMLReader and vice-versa.</p>

+ * See <a href='http://www.saxproject.org'>http://www.saxproject.org</a>
+ * for further information.
+ * </blockquote>
+ *
+ * <p><strong>Note:</strong> despite its name, this interface does 
+ * <em>not</em> extend the standard Java {@link java.io.Reader Reader} 
+ * interface, because reading XML is a fundamentally different activity 
+ * than reading character data.</p>
+ *
+ * <p>XMLReader is the interface that an XML parser's SAX2 driver must
+ * implement.  This interface allows an application to set and
+ * query features and properties in the parser, to register
+ * event handlers for document processing, and to initiate
+ * a document parse.</p>
+ *
+ * <p>All SAX interfaces are assumed to be synchronous: the
+ * {@link #parse parse} methods must not return until parsing
+ * is complete, and readers must wait for an event-handler callback
+ * to return before reporting the next event.</p>
+ *
+ * <p>This interface replaces the (now deprecated) SAX 1.0 {@link
+ * org.xml.sax.Parser Parser} interface.  The XMLReader interface
+ * contains two important enhancements over the old Parser
+ * interface (as well as some minor ones):</p>
+ *
+ * <ol>
+ * <li>it adds a standard way to query and set features and 
+ *  properties; and</li>
+ * <li>it adds Namespace support, which is required for many
+ *  higher-level XML standards.</li>
+ * </ol>
+ *
+ * <p>There are adapters available to convert a SAX1 Parser to
+ * a SAX2 XMLReader and vice-versa.</p>

+
+<p>
+This package contains interfaces to optional SAX2 handlers.
+
+<p>See <a href='http://www.saxproject.org'>http://www.saxproject.org</a>
+for more information about SAX.</p>
+
+<p>
+The package is independent of the SAX2 core, though the functionality
+exposed generally needs to be implemented within a parser.
+That independence has several consequences:</p>
+
+<ul>
+
+<li>SAX2 drivers are <em>not</em> required to recognize these handlers,
+and you cannot assume that the class files will be present in every SAX2
+installation.</li>
+
+<li>This package may be updated independently of SAX2 (i.e. new
+handlers may be added without updating SAX2 itself).</li>
+
+<li>The handlers are not implemented by the SAX2
+<code>org.xml.sax.helpers.DefaultHandler</code> or
+<code>org.xml.sax.helpers.XMLFilterImpl</code> classes.
+You can subclass these if you need such behaviour.</li>
+
+<li>The handlers need to be registered differently than regular SAX2
+handlers.</li>
+
+</ul>
+
+<p>This package, SAX2-ext, is a standardized extension to SAX2.  It is
+designed both to allow SAX parsers to pass certain types of information
+to applications, and to serve as a simple model for other SAX2 parser
+extension packages.  Not all such extension packages should need to
+be recognized directly by parsers, however.
+As an example, most schema systems can be cleanly layered on top
+of parsers supporting the standardized SAX2 interfaces.  </p>
+
+<p><strong>NOTE:</strong> this package alone does add any
+functionality; it simply provides optional interfaces for SAX2 drivers
+to use.  You must use a SAX2 driver that recognizes these interfaces if
+you actually want to have access to lexical and declaration
+information.</p>

- * <p>Please note that SAX parsers are not required to use this

-/**
- * Default implementation of the Attributes interface.
- *
- * <blockquote>
- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p>This class provides a default implementation of the SAX2
- * {@link org.xml.sax.Attributes Attributes} interface, with the 
- * addition of manipulators so that the list can be modified or 
- * reused.</p>
- *
- * <p>There are two typical uses of this class:</p>
- *
- * <ol>
- * <li>to take a persistent snapshot of an Attributes object
- *  in a {@link org.xml.sax.ContentHandler#startElement startElement} event; or</li>
- * <li>to construct or modify an Attributes object in a SAX2 driver or filter.</li>
- * </ol>
- *
- * <p>This class replaces the now-deprecated SAX1 {@link 
- * org.xml.sax.helpers.AttributeListImpl AttributeListImpl}
- * class; in addition to supporting the updated Attributes
- * interface rather than the deprecated {@link org.xml.sax.AttributeList
- * AttributeList} interface, it also includes a much more efficient 
- * implementation using a single array rather than a set of Vectors.</p>
- *
- * @since SAX 2.0

-/**
- * Encapsulate Namespace logic for use by SAX drivers.
- *
- * <blockquote>
- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p>This class encapsulates the logic of Namespace processing:
- * it tracks the declarations currently in force for each context
- * and automatically processes qualified XML 1.0 names into their
- * Namespace parts; it can also be used in reverse for generating
- * XML 1.0 from Namespaces.</p>
- *
- * <p>Namespace support objects are reusable, but the reset method
- * must be invoked between each session.</p>
- *
- * <p>Here is a simple session:</p>
- *
- * <pre>
- * String parts[] = new String[3];
- * NamespaceSupport support = new NamespaceSupport();
- *
- * support.pushContext();
- * support.declarePrefix("", "http://www.w3.org/1999/xhtml");
- * support.declarePrefix("dc", "http://www.purl.org/dc#");
- *
- * String parts[] = support.processName("p", parts, false);
- * System.out.println("Namespace URI: " + parts[0]);
- * System.out.println("Local name: " + parts[1]);
- * System.out.println("Raw name: " + parts[2]);
-
- * String parts[] = support.processName("dc:title", parts, false);
- * System.out.println("Namespace URI: " + parts[0]);
- * System.out.println("Local name: " + parts[1]);
- * System.out.println("Raw name: " + parts[2]);
-
- * support.popContext();
- * </pre>
- *
- * <p>Note that this class is optimized for the use case where most
- * elements do not contain Namespace declarations: if the same
- * prefix/URI mapping is repeated for each context (for example), this
- * class will be somewhat less efficient.</p>

+/**
+ * Encapsulate Namespace logic for use by applications using SAX,
+ * or internally by SAX drivers.

+ * <blockquote>
+ * <em>This module, both source code and documentation, is in the

+ * See <a href='http://www.saxproject.org'>http://www.saxproject.org</a>
+ * for further information.
+ * </blockquote>
+ *
+ * <p>This class encapsulates the logic of Namespace processing:
+ * it tracks the declarations currently in force for each context
+ * and automatically processes qualified XML 1.0 names into their
+ * Namespace parts; it can also be used in reverse for generating
+ * XML 1.0 from Namespaces.</p>
+ *
+ * <p>Namespace support objects are reusable, but the reset method
+ * must be invoked between each session.</p>
+ *
+ * <p>Here is a simple session:</p>
+ *
+ * <pre>
+ * String parts[] = new String[3];
+ * NamespaceSupport support = new NamespaceSupport();
+ *
+ * support.pushContext();
+ * support.declarePrefix("", "http://www.w3.org/1999/xhtml");
+ * support.declarePrefix("dc", "http://www.purl.org/dc#");
+ *
+ * parts = support.processName("p", parts, false);
+ * System.out.println("Namespace URI: " + parts[0]);
+ * System.out.println("Local name: " + parts[1]);
+ * System.out.println("Raw name: " + parts[2]);
+ *
+ * parts = support.processName("dc:title", parts, false);
+ * System.out.println("Namespace URI: " + parts[0]);
+ * System.out.println("Local name: " + parts[1]);
+ * System.out.println("Raw name: " + parts[2]);
+ *
+ * support.popContext();
+ * </pre>
+ *
+ * <p>Note that this class is optimized for the use case where most
+ * elements do not contain Namespace declarations: if the same
+ * prefix/URI mapping is repeated for each context (for example), this
+ * class will be somewhat less efficient.</p>
+ *
+ * <p>Although SAX drivers (parsers) may choose to use this class to
+ * implement namespace handling, they are not required to do so.
+ * Applications must track namespace information themselves if they
+ * want to use namespace information.
+ *
+ * @since SAX 2.0

+<h2> SAX2 Standard Feature Flags </h2>
+
+<p> One of the essential characteristics of SAX2 is that it added
+feature flags which can be used to examine and perhaps modify
+parser modes, in particular modes such as validation.
+Since features are identified by (absolute) URIs, anyone
+can define such features.   
+Currently defined standard feature URIs have the prefix
+<code>http://xml.org/sax/features/</code> before an identifier such as
+<code>validation</code>.  Turn features on or off using
+<em>setFeature</em>.  Those standard identifiers are: </p>
+
+
+<table border="1" cellpadding="3" cellspacing="0" width="100%">
+    <tr align="center" bgcolor="#ccccff">
+	<th>Feature ID</th>
+	<th>Default</th>
+	<th>Description</th>
+	</tr>
+
+    <tr>
+	<td>external-general-entities</td>
+	<td><em>unspecified</em></td>
+	<td> Reports whether this parser processes external
+	    general entities; always true if validating</td>
+	</tr>
+
+    <tr>
+	<td>external-parameter-entities</td>
+	<td><em>unspecified</em></td>
+	<td> Reports whether this parser processes external
+	    parameter entities; always true if validating</td>
+	</tr>
+
+    <tr>
+	<td>lexical-handler/parameter-entities</td>
+	<td><em>unspecified</em></td>
+	<td> true indicates that the LexicalHandler will report the
+	    beginning and end of parameter entities
+	    </td>
+	</tr>
+
+    <tr>
+	<td>namespaces</td>
+	<td>true</td>
+	<td> true indicates namespace URIs and unprefixed local names
+	    for element and attribute names will be available </td>
+	</tr>
+
+    <tr>
+	<td>namespace-prefixes</td>
+	<td>false</td>
+	<td> true indicates XML 1.0 names (with prefixes) and attributes
+	    (including <em>xmlns*</em> attributes) will be available </td>
+	</tr>
+
+    <tr>
+	<td>string-interning</td>
+	<td><em>unspecified</em></td>
+	<td> true if all XML names (for elements, prefixes, attributes,
+	    entities, notations, and local names),
+	    as well as Namespace URIs, will have been interned
+	    using <em>java.lang.String.intern</em>. This supports fast
+	    testing of equality/inequality against string constants.</td>
+	</tr>
+
+    <tr>
+	<td>validation</td>
+	<td><em>unspecified</em></td>
+	<td> controls whether the parser is reporting all validity
+	    errors; if true, all external entities will be read.  </td>
+	</tr>
+
+</table>
+
+<p> Support for the default values of the
+<em>namespaces</em> and <em>namespace-prefixes</em>
+properties is required.
+</p>
+
+<p> For default values not specified by SAX2,
+each XMLReader implementation specifies its default,
+or may choose not to expose the feature flag.
+Unless otherwise specified here,
+implementations may support changing current values
+of these standard feature flags, but not while parsing.
+</p>
+
+<h2> SAX2 Standard Handler and Property IDs </h2>
+
+<p> For parser interface characteristics that are described
+as objects, a separate namespace is defined.  The
+objects in this namespace are again identified by URI, and
+the standard property URIs have the prefix
+<code>http://xml.org/sax/properties/</code> before an identifier such as
+<code>lexical-handler</code> or
+<code>dom-node</code>.  Manage those properties using
+<em>setProperty()</em>.  Those identifiers are: </p>
+
+<table border="1" cellpadding="3" cellspacing="0" width="100%">
+    <tr align="center" bgcolor="#ccccff">
+	<th>Property ID</th>
+	<th>Description</th>
+	</tr>
+
+    <tr>
+	<td>declaration-handler</td>
+	<td> Used to see most DTD declarations except those treated
+	    as lexical ("document element name is ...") or which are
+	    mandatory for all SAX parsers (<em>DTDHandler</em>).
+	    The Object must implement <a href="ext/DeclHandler.html"
+	    ><em>org.xml.sax.ext.DeclHandler</em></a>.
+	    </td>
+	</tr>
+
+    <tr>
+	<td>dom-node</td>
+	<td> For "DOM Walker" style parsers, which ignore their
+	    <em>parser.parse()</em> parameters, this is used to
+	    specify the DOM (sub)tree being walked by the parser.
+	    The Object must implement the
+	    <em>org.w3c.dom.Node</em> interface.
+	    </td>
+	</tr>
+
+    <tr>
+	<td>lexical-handler</td>
+	<td> Used to see some syntax events that are essential in some
+	    applications:  comments, CDATA delimeters, selected general
+	    entity inclusions, and the start and end of the DTD
+	    (and declaration of document element name).
+	    The Object must implement <a href="ext/LexicalHandler.html"
+	    ><em>org.xml.sax.ext.LexicalHandler</em></a>.
+	    </td>
+	</tr>
+
+    <tr>
+	<td>xml-string</td>
+	<td> Readable only during a parser callback, this exposes a <b>TBS</b>
+	    chunk of characters responsible for the current event. </td>
+	</tr>
+
+</table>
+
+<p> All of these standard properties are optional;
+XMLReader implementations need not support them.
