-- Dimension Terminology --
---------------------------
-- * Dimensioned type
-- A dimensioned type is a type (more accurately a first subtype) to which
-- the aspect Dimension_System applies to.
-- type Mks_Type is new Long_Long_Float
-- with
-- Dimension_System => (
-- (Unit_Name => Meter, Unit_Symbol => 'm', Dim_Symbol => 'L'),
-- (Unit_Name => Kilogram, Unit_Symbol => "kg", Dim_Symbol => 'M'),
-- (Unit_Name => Second, Unit_Symbol => 's', Dim_Symbol => 'T'),
-- (Unit_Name => Ampere, Unit_Symbol => 'A', Dim_Symbol => 'I'),
-- (Unit_Name => Kelvin, Unit_Symbol => 'K', Dim_Symbol => "Θ"),
-- (Unit_Name => Mole, Unit_Symbol => "mol", Dim_Symbol => 'N'),
-- (Unit_Name => Candela, Unit_Symbol => "cd", Dim_Symbol => 'J'));
-- * Dimensioned subtype
-- A dimensioned subtype is a subtype directly defined from the dimensioned
-- type and to which the aspect Dimension applies to.
-- subtype Length is Mks_Type
-- with
-- Dimension => (Symbol => 'm',
-- Meter => 1,
-- others => 0);
