D.1. XHTML 1.1 Schema Driver

This section contains the driver for the XHTML 1.1 document type implementation as an XML Schema. It relies upon XHTML module implementations defined in [XHTMLMOD] and in [RUBY].

D.2. XHTML 1.1 Schema Modules

XHTML Family implementations using XML Schema are required to provide their own schema module that imports the required modules from XHTML Modularization.

D.3. XHTML 1.1 Customizations

An XHTML Family Document Type (such as XHTML 1.1) must define the content model that it uses. This is done through a separate content model module that is instantiated by the XHTML Modular Framework. The content model module and the XHTML 1.1 Driver (above) work together to customize the module implementations to the document type's specific requirements. The content model module for XHTML 1.1 is defined below:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    elementFormDefault="qualified"
    xmlns:xh11d="http://www.w3.org/1999/xhtml/datatypes/">
    <xs:import
        namespace="http://www.w3.org/1999/xhtml/datatypes/"
        schemaLocation="xhtml-datatypes-1.xsd"/>
    <xs:annotation>
        <xs:documentation> 
            This is the XML Schema module of common content models for XHTML11

            XHTML Document Model 
            This module describes the groupings of elements/attributes 
            that make up common content models for XHTML elements. 
            XHTML has following basic content models: 
               xhtml.Inline.mix; character-level elements
               xhtml.Block.mix; block-like elements, e.g., paragraphs and lists
               xhtml.Flow.mix; any block or inline elements 
               xhtml.HeadOpts.mix; Head Elements 
               xhtml.InlinePre.mix; Special class for pre content model 
               xhtml.InlineNoAnchor.mix; Content model for Anchor 
            
            Any groups declared in this module may be used to create 
            element content models, but the above are considered 'global' 
            (insofar as that term applies here). XHTML has the
            following Attribute Groups 
               xhtml.Core.extra.attrib 
               xhtml.I18n.extra.attrib
               xhtml.Common.extra 
            
            The above attribute Groups are considered Global
