This appendix is informative.
This Appendix describes the differences between XHTML 1.1 and XHTML 1.0. XHTML 1.1 represents a departure from both HTML 4.0 and XHTML 1.0. Most significant is the removal of features that were deprecated. In addition, some features that were available have been removed. In general, the strategy is to define a markup language that is rich in structural functionality, but that relies upon style sheets for presentation.
In the table below, each element present in XHTML 1.0 is listed. For each element the table indicates whether it is supported, and if so whether the contant model has changed and whether the available attributes have changed.
