Hi Fabien, thanks for releasing this, but I'm afraid you're right it's
kind of buggy. 8-)

The first quick look shows that the SAWSDL file you use is a strange
mixture of new and old WSDL elements (1.1 and 2.0), not valid in either
version; the RDF results use some old WSDL-RDF namespace, and in fact
most namespaces are slightly wrong (trailing / that shouldn't be there
in both WSDL and SAWSDL namespaces, for example). Also the component
identifiers are slightly wrong (the XPointer part should be a fragment
ID, i.e. after a # sign, and the xmlns namespace declarations in the
XPointer parts are unnecessary).

I suggest that you could use the files at the SAWSDL test suite [1] to
test the transform; it contains valid WSDL 1.1 and 2.0 files, plain and
annotated with SAWSDL annotations, and an expected RDF form for some of

[1] http://www.w3.org/2002/ws/sawsdl/CR/testsuite.html

Looking forward to seeing the next version, and I'll be glad to do some
quick testing on it if you guys want me to. 8-)

Best regards,
