+<!-- XHTML 1.1 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.
