F. XHTML DTD Module Implementations

Contents

This appendix is normative.

This appendix will contain implementations of the modules defined in XHTML Abstract Modules via XML DTDs. These module implementations can be used by XHTML Family Document Types.

F.1. XHTML Character Entities

XHTML DTDs make available a standard collection of named character entities. Those entities are defined in this section.

F.1.1. XHTML Latin 1 Character Entities

<!-- ...................................................................... -->
<!-- XML-compatible ISO Latin 1 Character Entity Set for XHTML ............ -->
<!-- file: xhtml-lat1.ent

     Typical invocation:

       <!ENTITY % xhtml-lat1
           PUBLIC "-//W3C//ENTITIES Latin 1 for XHTML//EN"
                  "xhtml-lat1.ent" >
       %xhtml-lat1;

     This DTD module is identified by the PUBLIC and SYSTEM identifiers:

     PUBLIC "-//W3C//ENTITIES Latin 1 for XHTML//EN"
     SYSTEM "xhtml-lat1.ent"

F.2. XHTML Modular Framework

In order to take advantage of the XHTML DTD Modules, DTD authors need to define the content model for their DTD. XHTML provides a variety of tools to ease this effort. They are defined in a set of support modules, instantiated by a main Framework module:

<!-- Modular Framework

     This required module instantiates the modules needed
     to support the XHTML modularization model, including:

        +  notations
        +  datatypes
        +  namespace-qualified names
        +  common attributes
        +  document model
        +  character entities

     The Intrinsic Events module is ignored by default but
     occurs in this module because it must be instantiated
     prior to Attributes but after Datatypes.

<!-- XHTML Qname (Qualified Name) Module

     This module is contained in two parts, labeled Section 'A' and 'B':

       Section A declares parameter entities to support namespace-
       qualified names, namespace declarations, and name prefixing 
       for XHTML and extensions.
    
       Section B declares parameter entities used to provide
       namespace-qualified names for all XHTML element types:

         %applet.qname;   the xmlns-qualified name for <applet>
         %base.qname;     the xmlns-qualified name for <base>
         ...

     XHTML extensions would create a module similar to this one. 
     Included in the XHTML distribution is a template module 
     ('template-qname-1.mod') suitable for this purpose.
-->

<!-- Section A: XHTML XML Namespace Framework :::::::::::::::::::: -->

<!-- 1. Declare a %XHTML.prefixed; conditional section keyword, used
        to activate namespace prefixing. The default value should 
        inherit '%NS.prefixed;' from the DTD driver, so that unless 
        overridden, the default behaviour follows the overall DTD 
        prefixing scheme.
-->

<!-- 2. Declare a parameter entity (eg., %XHTML.xmlns;) containing 
        the URI reference used to identify the XHTML namespace:
-->
<!ENTITY % XHTML.xmlns  "http://www.w3.org/1999/xhtml" >

<!-- 3. Declare parameter entities (eg., %XHTML.prefix;) containing
        the default namespace prefix string(s) to use when prefixing 
        is enabled. This may be overridden in the DTD driver or the
        internal subset of an document instance. If no default prefix
        is desired, this may be declared as an empty string.

     NOTE: As specified in [XMLNAMES], the namespace prefix serves 
     as a proxy for the URI reference, and is not in itself significant.
-->
<!ENTITY % XHTML.prefix  "" >

<!-- 4. Declare parameter entities (eg., %XHTML.pfx;) containing the 
        colonized prefix(es) (eg., '%XHTML.prefix;:') used when 
        prefixing is active, an empty string when it is not.

        redeclared to contain any non-XHTML namespace declaration 
        attributes for namespaces embedded in XHTML. The default 
        is an empty string.  XLink should be included here if used 
        in the DTD.

<!-- The remainder of Section A is only followed in XHTML, not extensions. -->

     Such a DTD should be named with a variant FPI and redeclare
     the value of the %XHTML.version; parameter entity to that FPI:

     IMPORTANT:  see also the notes included in the Legacy Redeclarations
     Module for information on how to construct a DTD using this module.

<!-- XHTML Qname (Qualified Name) Module

     This module is contained in two parts, labeled Section 'A' and 'B':

       Section A declares parameter entities to support namespace-
       qualified names, namespace declarations, and name prefixing 
       for XHTML and extensions.
    
       Section B declares parameter entities used to provide
       namespace-qualified names for all XHTML element types:

         %applet.qname;   the xmlns-qualified name for <applet>
         %base.qname;     the xmlns-qualified name for <base>
         ...

     XHTML extensions would create a module similar to this one. 
     Included in the XHTML distribution is a template module 
     ('template-qname-1.mod') suitable for this purpose.
-->

<!-- Section A: XHTML XML Namespace Framework :::::::::::::::::::: -->

<!-- 1. Declare a %XHTML.prefixed; conditional section keyword, used
        to activate namespace prefixing. The default value should 
        inherit '%NS.prefixed;' from the DTD driver, so that unless 
        overridden, the default behaviour follows the overall DTD 
        prefixing scheme.
-->
<!ENTITY % NS.prefixed "IGNORE" >
<!ENTITY % XHTML.prefixed "%NS.prefixed;" >

<!-- 2. Declare a parameter entity (eg., %XHTML.xmlns;) containing 
        the URI reference used to identify the XHTML namespace:
-->
<!ENTITY % XHTML.xmlns  "http://www.w3.org/1999/xhtml" >

<!-- 3. Declare parameter entities (eg., %XHTML.prefix;) containing
        the default namespace prefix string(s) to use when prefixing 
        is enabled. This may be overridden in the DTD driver or the
        internal subset of an document instance. If no default prefix
        is desired, this may be declared as an empty string.

     NOTE: As specified in [XMLNAMES], the namespace prefix serves 
     as a proxy for the URI reference, and is not in itself significant.
-->
<!ENTITY % XHTML.prefix  "" >

<!-- 4. Declare parameter entities (eg., %XHTML.pfx;) containing the 
        colonized prefix(es) (eg., '%XHTML.prefix;:') used when 
        prefixing is active, an empty string when it is not.

        redeclared to contain any non-XHTML namespace declaration 
        attributes for namespaces embedded in XHTML. The default 
        is an empty string.  XLink should be included here if used 
        in the DTD.
-->
<!ENTITY % XHTML.xmlns.extra.attrib "" >

<!-- The remainder of Section A is only followed in XHTML, not extensions. -->

     prefixing is active.
