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]).
