Attribute Types
===============

   Basic types for attributes are names and values.  (See note about
names in Note: Types.) And attribute values (attval) by lisp strings.

Attribute Declaration List Type
-------------------------------

 - Data type: attlist attdecl*
     This is the result of the ATTLIST declarations in the DTD.  All
     attribute declarations for an element is the elements attlist.

 - Function: sgml-lookup-attdecl name attlist
     Return attribute declaration (attdecl) for attribute NAME in
     attribute declaration list ATTLIST.

 - Function: sgml-attribute-with-declared-value attlist declared-value
     Find the first attribute in ATTLIST that has DECLARED-VALUE.

Attribute Declaration Type
--------------------------

 - Data type: attdecl name declared-value default-value
     This is the representation of an individual attribute declaration
     contained in an ATTLIST declaration.

 - Function: sgml-make-attdecl name declared-value default-value
     Produces an attdecl.

 - Function: sgml-attdecl-name attdecl
     Returns the name of an attribute declaration.

 - Function: sgml-attdecl-declared-value attdecl
     Returns the declared-value of attribute declaration ATTDECL.

 - Function: sgml-attdecl-default-value: attdecl
     Returns the default-value of attribute declaration ATTDECL.

Declared Value Type
-------------------

 - Data type: declared-value (token-group | notation | simple)
     A declared value of an SGML attribute can be of different kinds.
     If the declared value is a token group there is an associated list
     of name tokens.  For notation there is also a list of associated
     names, the allowed notation names.  The other declared values are
     represented by the type name as a lisp symbol.

 - Function: sgml-declared-value-token-group declared-value
     Return the name token group for the DECLARED-VALUE.  This applies
     to name token groups.  For other declared values nil is returned.

 - Function: sgml-declared-value-notation declared-value
     Return the list of notation names for the DECLARED-VALUE.  This
     applies to notation declared value.  For other declared values nil
     is returned.

Default Value Type
------------------

 - Data type: default-value (required | implied | conref | specified )
     There are several kinds of default values.  The REQUIRED, IMPLIED,
     and CONREF has no associated information.  The SPECIFIED have an
     associated attribute value and can be either `fixed' or `normal'.

 - Function: sgml-make-default-value type &optional attval

 - Function: sgml-default-value-attval default-value
     Return the actual default value of the declared DEFAULT-VALUE.
     The actual value is a string. Return `nil' if no actual value.

 - Function: sgml-default-value-type-p type default-value
     Return true if DEFAULT-VALUE is of TYPE.  Where TYPE is a symbol,
     one of `required', `implied', `conref', or `fixed'.

Attribute Specification Type
----------------------------

 - Data type: attspec name attval
     This is the result of parsing an attribute specification.

 - Function: sgml-make-attspec name attval
     Create an attspec from NAME and ATTVAL.  Special case, if ATTVAL
     is `nil' this is an implied attribute.

 - Function: sgml-attspec-name attspec
     Return the name of the attribute specified by ATTSPEC.

 - Function: sgml-attspec-attval attspec
     Return the value (attval) of attribute specification ATTSPEC.  If
     ATTSPEC is `nil', `nil' is returned.

Attribute Specification List Type
---------------------------------

 - Data type: asl attspec*
     This is the result of parsing an attribute specification list.

 - Function: sgml-lookup-attspec name asl
     Return the attribute specification for attribute with NAME in the
     attribute specification list ASL.  If the attribute is unspecified
     `nil' is returned.
