+
+<!-- XHTML+RDFa 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 parameter entities 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).
+
+     The reserved word '#PCDATA' (indicating a text string) is now
+     included explicitly with each element declaration that is
+     declared as mixed content, as XML requires that this token
+     occur first in a content model specification.
+-->
+<!-- Extending the Model
+
+     While in some cases this module may need to be rewritten to
+     accommodate changes to the document model, minor extensions
+     may be accomplished by redeclaring any of the three *.extra;
+     parameter entities to contain extension element types as follows:
+
+         %Misc.extra;    whose parent may be any block or
+                         inline element.
+
+         %Inline.extra;  whose parent may be any inline element.
+
+         %Block.extra;   whose parent may be any block element.
+
+     If used, these parameter entities must be an OR-separated
+     list beginning with an OR separator ("|"), eg., "| a | b | c"
+
+     All block and inline *.class parameter entities not part
+     of the *struct.class classes begin with "| " to allow for
+     exclusion from mixes.
