    A. Changes from XHTML 1.0 Strict

    This appendix is informative.

    This Appendix describes the differences between XHTML 1.1 and
    XHTML 1.0 Strict. XHTML 1.1 represents a departure from both HTML
    4 and XHTML 1.0. Most significant is the removal of features that
    were deprecated. In general, the strategy is to define a markup
    language that is rich in structural functionality, but that relies
    upon style sheets for presentation.

    The differences can be summarized as follows:

       1. On every element, the lang attribute has been removed in
          favor of the xml:lang attribute (as defined in [XHTMLMOD]).

       2. On the a and map elements, the name attribute has been
          removed in favor of the id attribute (as defined in
          [XHTMLMOD]).

       3. The "ruby" collection of elements has been added (as defined
          in [RUBY]).

And from the XHTML 1.0 recommandation
http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_XHTML-1.0-Strict

    Extensible HTML version 1.0 Strict DTD

    This is the same as HTML 4 Strict except for changes due to the
    differences between XML and SGML.

Of course that excludes markup which is part of HTML4 Transitional or
Frameset but is not part of Strict.
