-// Marshal writes an XML-formatted representation of v to w.
-//
-// If v implements Marshaler, then Marshal calls its MarshalXML method.
-// Otherwise, Marshal uses the following procedure to create the XML.
-//
-// Marshal handles an array or slice by marshalling each of the elements.
-// Marshal handles a pointer by marshalling the value it points at or, if the
-// pointer is nil, by writing nothing.  Marshal handles an interface value by
-// marshalling the value it contains or, if the interface value is nil, by
-// writing nothing.  Marshal handles all other data by writing one or more XML
-// elements containing the data.
-//
-// The name for the XML elements is taken from, in order of preference:
-//     - the tag on an XMLName field, if the data is a struct
-//     - the value of an XMLName field of type xml.Name
-//     - the tag of the struct field used to obtain the data
-//     - the name of the struct field used to obtain the data
-//     - the name '???'.
-//
-// The XML element for a struct contains marshalled elements for each of the
-// exported fields of the struct, with these exceptions:
-//     - the XMLName field, described above, is omitted.
-//     - a field with tag "attr" becomes an attribute in the XML element.
-//     - a field with tag "chardata" is written as character data,
-//        not as an XML element.
-//     - a field with tag "innerxml" is written verbatim,
-//        not subject to the usual marshalling procedure.
-//
-// If a field uses a tag "a>b>c", then the element c will be nested inside
-// parent elements a and b.  Fields that appear next to each other that name
-// the same parent will be enclosed in one XML element.  For example:
-//
-//	type Result struct {
-//		XMLName   xml.Name `xml:"result"`
-//		FirstName string   `xml:"person>name>first"`
-//		LastName  string   `xml:"person>name>last"`
-//		Age       int      `xml:"person>age"`
-//	}
-//
-//	xml.Marshal(w, &Result{FirstName: "John", LastName: "Doe", Age: 42})
-//
-// would be marshalled as:
-//
-//	<result>
-//		<person>
-//			<name>
-//				<first>John</first>
-//				<last>Doe</last>
-//			</name>
-//			<age>42</age>
-//		</person>
-//	</result>
-//

-// BUG(rsc): Mapping between XML elements and data structures is inherently flawed:
-// an XML element is an order-dependent collection of anonymous
-// values, while a data structure is an order-independent collection
-// of named values.
-// See package json for a textual representation more suitable
-// to data structures.
-
-// Unmarshal parses an XML element from r and uses the
-// reflect library to fill in an arbitrary struct, slice, or string
-// pointed at by val.  Well-formed data that does not fit
-// into val is discarded.
-//
-// For example, given these definitions:
-//
-//	type Email struct {
-//		Where string `xml:"attr"`
-//		Addr  string
-//	}
-//
-//	type Result struct {
-//		XMLName xml.Name `xml:"result"`
-//		Name	string
-//		Phone	string
-//		Email	[]Email
-//		Groups  []string `xml:"group>value"`
-//	}
-//
-//	result := Result{Name: "name", Phone: "phone", Email: nil}
-//
-// unmarshalling the XML input
-//
-//	<result>
-//		<email where="home">
-//			<addr>gre@example.com</addr>
-//		</email>
-//		<email where='work'>
-//			<addr>gre@work.com</addr>
-//		</email>
-//		<name>Grace R. Emlin</name>
-// 		<group>
-// 			<value>Friends</value>
-// 			<value>Squash</value>
-// 		</group>
-//		<address>123 Main Street</address>
-//	</result>
-//
-// via Unmarshal(r, &result) is equivalent to assigning
-//
-//	r = Result{xml.Name{"", "result"},
-//		"Grace R. Emlin", // name
-//		"phone",	  // no phone given
-//		[]Email{
-//			Email{"home", "gre@example.com"},
-//			Email{"work", "gre@work.com"},
-//		},
-//		[]string{"Friends", "Squash"},
-//	}
-//
-// Note that the field r.Phone has not been modified and
-// that the XML <address> element was discarded. Also, the field
-// Groups was assigned considering the element path provided in the
-// field tag.
-//
-// Because Unmarshal uses the reflect package, it can only assign
-// to exported (upper case) fields.  Unmarshal uses a case-insensitive
-// comparison to match XML element names to struct field names.
-//
-// Unmarshal maps an XML element to a struct using the following rules.
-// In the rules, the tag of a field refers to the value associated with the
-// key 'xml' in the struct field's tag (see the example above).
-//
-//   * If the struct has a field of type []byte or string with tag "innerxml",
-//      Unmarshal accumulates the raw XML nested inside the element
-//      in that field.  The rest of the rules still apply.
-//
-//   * If the struct has a field named XMLName of type xml.Name,
-//      Unmarshal records the element name in that field.
-//
-//   * If the XMLName field has an associated tag of the form
-//      "name" or "namespace-URL name", the XML element must have
-//      the given name (and, optionally, name space) or else Unmarshal
-//      returns an error.
-//
-//   * If the XML element has an attribute whose name matches a
-//      struct field of type string with tag "attr", Unmarshal records
-//      the attribute value in that field.
-//
-//   * If the XML element contains character data, that data is
-//      accumulated in the first struct field that has tag "chardata".
-//      The struct field may have type []byte or string.
-//      If there is no such field, the character data is discarded.
-//
-//   * If the XML element contains comments, they are accumulated in
-//      the first struct field that has tag "comments".  The struct
-//      field may have type []byte or string.  If there is no such
-//      field, the comments are discarded.
-//
-//   * If the XML element contains a sub-element whose name matches
-//      the prefix of a tag formatted as "a>b>c", unmarshal
-//      will descend into the XML structure looking for elements with the
-//      given names, and will map the innermost elements to that struct field.
-//      A tag starting with ">" is equivalent to one starting
-//      with the field name followed by ">".
-//
-//   * If the XML element contains a sub-element whose name
-//      matches a field whose tag is neither "attr" nor "chardata",
-//      Unmarshal maps the sub-element to that struct field.
-//      Otherwise, if the struct has a field named Any, unmarshal
-//      maps the sub-element to that struct field.
-//
-// Unmarshal maps an XML element to a string or []byte by saving the
-// concatenation of that element's character data in the string or
-// []byte.
-//
-// Unmarshal maps an attribute value to a string or []byte by saving
-// the value in the string or slice.
-//
-// Unmarshal maps an XML element to a slice by extending the length of
-// the slice and mapping the element to the newly created value.
-//
-// Unmarshal maps an XML element or attribute value to a bool by
-// setting it to the boolean value represented by the string.
-//
-// Unmarshal maps an XML element or attribute value to an integer or
-// floating-point field by setting the field to the result of
-// interpreting the string value in decimal.  There is no check for
-// overflow.
-//
-// Unmarshal maps an XML element to an xml.Name by recording the
-// element name.
-//
-// Unmarshal maps an XML element to a pointer by setting the pointer
-// to a freshly allocated value and then mapping the element to that value.
