http://www.w3.org/TR/xmlschema11-1/#declare-annotation seems to indicate 
that xsd:annotation is a valid element, as does 
http://www.w3.org/TR/xmlschema-1/#declare-annotation .

We're not in a position here to debug wsdl2java, though if you can show 
us a problem with the SPARQL WSDL, we'll gladly address it.

I can retrieve xml.xsd fine at http://www.w3.org/2001/xml.xsd. I don't 
see where xsi.xsd is referenced?

If you could point more directly to where you believe there are 
problems, that would help us out.

FYI, at the moment, most of the group's attention is focused on the 
query language and the protocol specifications, rather than the WSDL 1.1 
working draft.
