D. XHTML Schema Module Implementations

Contents

This appendix is normative.

This appendix contains implementations of the modules defined in XHTML Abstract Modules via XML Schema [XMLSCHEMA] when the XML Schema becomes a W3C approved recommendation.

D.1. XHTML Abstract Modules and XML Schema

The DTD modularization framework specification speaks at length on the subject of abstract modules. In brief, an "abstract" module is simply a set of objects, in this case objects within an ordered hierarchy of content objects, which encapsulates all of the features of the objects and assembles them into a coherent set. This set of objects and their properties is independent of its machine representation, and so is the same whether written in DTD module form, as a Schema module, or as a Java class.

The abstract modules described in XHTML-MOD are composed in a functional manner, and each "abstract module" contains data structures that are generally functionally similar. (There is no requirement that modules be created along functional lines; any other method that suits the author's purpose may be used instead.)

The framework described here makes use of the same abstract modules as in XHTML-MOD with few exceptions. In the case of the schema module representation, the relationship between the "abstract" modules and the schema modules is quite close. In each case there is a one-to-one relationship between the abstract and concrete modules (with one exception for the changes to the legacy module) and they share essentially the same names and data structures.

D.2. XHTML Schema Modules

D.2.1. XHTML Hub Document

This is the base schema document that includes all the other modules to create the complete schema.

The hub document included here intends to approximate XHTML 1.1 subject to the requirements given in Requirements. This schema should be fully equivalent to the DTD version except for schema-specific additions and changes. Any document instance considered valid using the XHTML 1.1 DTD must also be valid according to this schema.

D.3. XHTML SCHEMA Modular Framework

In order to take advantage of the XHTML Schema Modules, Schema authors need to define the content model for their language. 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:

        Basic Forms

        This forms module is based on the HTML 3.2 forms model, with
        the WAI-requested addition of the label element. While this 
        module essentially mimics the content model and attributes of 
        HTML 3.2 forms, the element types declared herein also include
        all HTML 4 common attributes.

        Elements defined here:
        form, label, input, select, option, textarea

        Basic Tables
    
        * table, caption, tr, th, td
    
         This table module declares elements and attributes defining
         a table model based fundamentally on features found in the
         widely-deployed HTML 3.2 table model.  While this module
         mimics the content model and table attributes of HTML 3.2
         tables, the element types declared herein also includes all
         HTML 4 common and most of the HTML 4 table attributes.

     Base element
    
            base
    
         This module declares the base element type and its attributes,
         used to define a base URI against which relative URIs in the
         document will be resolved.
    
         Note that this module also redeclares the content model for
         the head element to include the base element.

            (plus additional datatypes and attributes)
            
            This optional module declares additional markup for simple
            presentation-related markup based on features found in the
            HTML 4.0 Transitional and Frameset DTDs. This relies on
            inclusion of the Legacy Redeclarations module. This module
            also declares the frames, inline frames and object modules.
            
            This is to allow XHTML documents to be transformed for
            display on HTML browsers where CSS support is inconsistent
            or unavailable.

    XHTML Document Model

     This module describes the groupings of elements that make up
     common content models for XHTML elements.

     XHTML has three basic content models:

         Inline.mix;  character-level elements
         Block.mix;   block-like elements, eg., paragraphs and lists
         Flow.mix;    any block or inline elements

    Any groups declared in this module may be used
     to create element content models, but the above three are
     considered 'global' (insofar as that term applies here).
