------- Comment #8 from ot@w3.org  2007-03-16 12:55 -------
rewriting the parse mode selection routine entirely fixes this.

http://lists.w3.org/Archives/Public/www-validator-cvs/2007Mar/0095.html
has the CVS diff for the refactoring.

The logic goes:
* if neither content type nor doctype are helpful, 
  => throw warning, use SGML as fallback
* in case of an unknown doctype but useful mime type 
  (generally, XML mime type)
  => follow the mime type
* in case of an ambiguous mime type (text/html) but well-known doctype
  (any HTML served as text/html...)
  => follow the doctype 
* if neither are ambiguous, but they collide
  => throw warning, follow the mime type

This was tested with the documents in the catalogue, documents outside the
catalogue (custom DTDs), document served with the wrong mime type (XHTML 1.1 as
text/html, html 4.01 as application/xhtml+xml etc.) successfully, see:
http://qa-dev.w3.org/wmvs/HEAD/dev/tests/

Considering this fixed. If reopening, please provide clear test cases, thank
you.
