This is documented in Appendix B of the specification.

Emacs-w3 supports some if not all of the mentioned features. That's why
most XHTML documents are not displayed properly in that browser.

Justification? Errata is for errors, SHORTTAG the way it is declared is
not an error, it's been the same in HTML 3.2, HTML 4.0, the later
released HTML 4.0 and finally HTML 4.01. There is no good reason to
change the SGML declaration and thus turn valid documents into invalid
documents. The W3C MarkUp Validator may warn authors using such features
if you like it to, without any change to the specification.
