The W3C XHTML working group has published proposed edited recommendations of 4 XHTML 1.1 specs:
- XHTML™ Basic 1.1 - Second Edition: "In this revision, an XML Schema implementation and the lang attribute have been added." (A schema is fine, but a new attribute is really beyond what a merely edited recommendation should offer.The problem is the W3C process is too heavyweight and hidebound, and mixes experimentation with standardization, so even the W3C doesn't really follow it except in name any more.)
- XHTML-Print - Second Edition: "The only substantive changes in this version are the addition of an implementation of the markup language using XML Schema."
- XHTML™ 1.0: The Extensible HyperText Markup Language (Third Edition): "The only change of note in this version is that the contents of the informative Appendix A have been removed as they are being kept up to date in a separate document"
- XHTML™ 1.1 - Module-based XHTML - Second Edition: "It also includes an XML Schema implementation of the language, and integrates the lang attribute to increase compatibility with User Agents and Assistive Technologies."
