            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
