So, here's the problem... the SPARQL below evaluates to "false" when run
against PyRDFa's output for TC100. Note that I cut-paste the output of
PyRDFa directly into the SPARQL, so there shouldn't be any issues with
typo's. I tried to get this to work for a good 2 hours over the
weekend... and I can't see any reason why it shouldn't work other than
the @parseType being used instead of the @datatype. It might be a bug in
SPARQL.org? I'll e-mail Andy and see what he thinks.

ASK WHERE {
<http://www.example.org> <http://example.org/rdf/example> "Some text
here in <strong xmlns=\"http://www.w3.org/1999/xhtml\"
xmlns:svg=\"http://www.w3.org/2000/svg\">bold</strong> and an svg
rectangle: <svg:svg xmlns=\"http://www.w3.org/1999/xhtml\"
xmlns:svg=\"http://www.w3.org/2000/svg\"><svg:rect svg:height=\"100\"
svg:width=\"200\"/></svg:svg>"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral>
 .
}

In short, I believe that there's an issue between using @parseType and
@datatype... and I don't know how to get around it in the SPARQL query.
