#43 Question marks in SPARQL Results name attribute

[tomheath]

SPARQL results from a RAP DbModel are coming back with question marks in the name attributes of variable and result/binding elements. E.g.

<result>
<binding name="?thing"><uri>http://some/uri</uri></binding>
<binding name="?name"><literal>Some Name or Label</literal></binding>
<binding name="?review"><uri>http://some/review/uri</uri></binding>
<binding name="?createdOn"><literal>2007-01-01T00:00:01-08:00</literal></binding>
</result>

This appears to be in contradiction to the SPARQL Query Results XML Format.
