hmmm. ok let's see the practical side.

1. The validator indeed accepts everything and judge by what is sent  
to it

2. So far sending XHTML 1.1 as application/xhtml+xml is wrong

3. Accept Header application/xhtml+xml is at work for the validator.
    (Note btw, that once the validator sends accept header  
application, the
     configuration mistake of Sierk would not be detected, which is  
bad too)

4. When a user agent says "accept everything", it does NOT mean  
"render everything".
    (For example, one thing I was doing in the past with user agent  
which didn't
     support application/xhtml+xml is to put the handler to open the  
document with
     Mozilla. We do the same thing for example with RSS feed, open  
with my RSS
     feed reader.)

5. User agent sniffing is not very practical and leads to bad choices.


The validator did the right thing in this case and at the time being:
     an XHTML 1.1 document is sent with text/html.  Wrong.

I wonder if Sierk is using ruby markup in his pages. If not, your  
document could be XHTML 1.0.
