application/xhtml+xml

Hello,

Some XHTML 1.0 web sites send different mime types to user agents, 
depending of their HTTP Accept values :

- Web sites send application/xhtml+xml to user agents which are able to 
manage this mime type.

- They send text/html to other user agents.

Unfortunately, the W3C html validator does not inform the web site of 
its ability to deal with application/xhtml+xml.

It would be nice if the validator could accept application/xhtml+xml in 
its HTTP GET requests.

Just add the word « application/xhtml+xml » in the Accept string of the 
W3C Validator. Here is an example of Mozilla Firefox Accept string, 
which contains the « application/xhtml+xml » word :

Accept: 
application/x-shockwave-flash,text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,*/*;q=0.1

Sincerely,
