Error in SAWSDL-0G baseline

Woden is failing this new testcase but I think it's because there's an error
in the canonical baseline.

There are 2 interfaceMessageReferences each with an elementDeclaration child
which Woden's canonical wsdlcm reports as:

<elementDeclaration ref="c6" /> and <elementDeclaration ref="c6" />

The baseline canonical wsdlcml reports these as:

<elementDeclaration /> and <elementDeclaration />  (i.e. no 'ref' attribute)
