There is some schema parsing stuff here in the webservices commons:
http://svn.apache.org/viewcvs.cgi/webservices/commons/trunk/XmlSchema/
It sounds like you might be going a step beyond just parsing things into
a schema oject model though?

Hi all,
We're planning to use Axis2 in Taverna to construct SOAP requests,
probably not using any form of data binding as we have our own and
just using the send / receive SOAP body functionality.
This means we have to be able to inspect arbitrary WSDL documents and
determine the input schema in such a way that we can present
appropriate 'input' and 'output' ports on our workflow components -
this is slightly non trivial as we can attempt to split up sequence
elements on input documents into different inputs and suchlike.
Until recently we were using the WSIF library to present a slightly
friendlier interface on the schema support in WSDL4J but changes in
the latter have broken this for the time being.
It occurs to me that our requirement is probably not unique, and that
it might be useful for the more message driven approach in Axis2 to
have richer schema support for type declarations in WSDL definitions.
Unless anyone knows of a really good existing lightweight Java model
for schema (I've looked but no luck) that can be glued into WSDL4J's
Definition model we're going to write one - the purpose being to
inspect a WSDL file and, for a given operation, provide enough
information in a friendly and easy to digest form for a dynamic
invoker to build a compliant request document / parse a response. Note
that this is _not_ a databinding layer, just type metadata. Actual
databinding could obviously be driven off it though.
1) Does this exist?
2) Would anyone else use it?
3) We're happy to contribute it to Axis2, to any other project or to
manage it ourselves, any preferences?
Cheers,
Tom
