+
+     This optional module declares additional markup for simple
+     presentation-related markup based on features found in the
+     HTML 4 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 1.1 documents to be transformed for
+     display on HTML browsers where CSS support is inconsistent
+     or unavailable.
+-->
+<!-- Constructing a Legacy DTD
+
+     To construct a DTD driver obtaining a close approximation
+     of the HTML 4 Transitional and Frameset DTDs, declare the
+     Legacy Redeclarations module as the pre-framework redeclaration
+     parameter entity (%xhtml-prefw-redecl.mod;) and INCLUDE its
+     conditional section:

+        ...

+        %xhtml-prefw-redecl.mod;]]>
+
+     Such a DTD should be named with a variant FPI and redeclare
+     the value of the %XHTML.version; parameter entity to that FPI:
+
+         "-//Your Name Here//DTD XHTML Legacy 1.1//EN"
+
+     IMPORTANT:  see also the notes included in the Legacy Redeclarations
+     Module for information on how to construct a DTD using this module.

+       for XHTML and extensions.
+
+       Section B declares parameter entities used to provide
+       namespace-qualified names for all XHTML element types:
+
+         %applet.qname;   the xmlns-qualified name for <applet>
+         %base.qname;     the xmlns-qualified name for <base>
+         ...
+
+     XHTML extensions would create a module similar to this one.
+     Included in the XHTML distribution is a template module
+     ('template-qname-1.mod') suitable for this purpose.
