It doesn't matter :) Again the example of source code below.

The fact that "it might be" is not relevant here BUT... (follow me a  
bit more)

What we could do, but we have to see with olivier and public-qa-dev  
community, is to have an additional option:

* Validate this document with this mime-type
    - text/html
    - application/xhtml+xml
    - etc.

There are options for encodings and document types already, look at  
the validator right now and [beta][1]. It complicates a bit more and  
might lead to usability problems. We, all of us, have to think about it.

But in the case it would be a reasonable option, as you proposed  
earlier for RDFa, would you be  ready to develop the perl code for it?

Many thanks
