Regardless of my previous comments on implementability; if we indeed 
accept this (and, in my purist moments, I tend to agree with Johannes on 
that one) this may affect our test suite.

Indeed, consider the following, slightly more complicated case:

<div about="">
       <h2 property="dc:title"><span class="bla">E = mc<sup>2</sup>: The 
Most Urgent Problem of Our Time</span></h2>
</div>

Then the generated RDF can either be:

<> <dc:title> "<span xmlns="http://www.w3.org/1999/xhtml" class="bla">E 
= mc<sup>2</sup>: The Most Urgent Problem of Our 
Time</span>"^^xsd:XMLLiteral

but it could also be:

<> <dc:title> "<span xmlns="http://www.w3.org/1999/xhtml" class="bla">E 
= mc<sup xmlns="http://www.w3.org/1999/xhtml>2</sup>: The Most Urgent 
Problem of Our Time</span>"^^xsd:XMLLiteral

which is, from an XML point of view, identical. The problem is that I am 
simply not sure whether the SPARQL engines compare XML Literals 
textually or 'semantically', so to say...
