OK, my mistake. I misread section 4 (I missed the fact that the '&' and 
';' would be passed through too).

But looking through the list of MathML named entities[1] it looks as 
tho' there's plenty there which could cause a lot of trouble in an 
encoding declaration. Aside from the XML magic five and the MathML 
whitespace entities, how about,

  <?xml encoding&equals;"UTF-8+names"?>
  <?xml version="1&dot;0" encoding="UTF-8+names"?>
  <?xml encoding="UTF-8&plus;names"?>

So I think we need a complete list of the predefined entities from XHTML 
and MathML which _aren't_ covered by sections 6 and 7. 

Cheers,
