This doesn't make sense at all in my opinion. You can't just fit together  
some snippets and expect the document to be valid. Consider for example  
that you validate the following surrounded by the dummy content


It validates fine of course, so you put it somewhere in the document


Oops. Not valid anymore. You're then back to square one, trying to figure  
out why the _whole_ document doesn't validate.

I also suspect that this will lead to questions such as "these two  
snippets validate fine, but when I put them together it doesn't validate  
anymore. Is the validator broken??!?1".
