Modularization of XHTML - XHTML DTD Module Implementations

# 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:

## 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:

    <!-- ...................................................................... -->
    <!-- XHTML Modular Framework Module  ...................................... -->
    <!-- file: xhtml-framework-1.mod

         This is XHTML, a reformulation of HTML as a modular XML application.

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

    <!-- 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.

         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.

    <!-- Legacy Redeclarations

         This optional module replaces the Modular Framework module, interspersing
         redeclarations of various parameter entities to allow for inclusions of
         Transitional markup in the XHTML 1.1 document model. This instantiates
         the modules needed to support the XHTML modularization model, including:

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

         By default, the Object module is included, with Frames and IFrames ignored.

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