Is the workflow running as a stand alone process as opposed to started
as an OSGi application? In that case no plugin registration takes
places and hence registrations of which factories are associated with
which file extensions are likely to be missing.

It tells it to write a schema location if the ePackage.nsURI() is
different from ePackage.eResource().getURI().

Rather than write out the location URI, it writes out the name of the
EPackage's generated interface, e.g, java:org.example.XyzPackage (or
something like that).

By default for generated models, the package's nsURI and the package's
resource's URI are the same.

I don't think this will solve the problem. For a model based on an XML
Schema, it's important that an XMLResourceImpl configured with options
like what you see in your generated XyzResourceFactoryImpl as used.

No. Try to find out from the oAW folks how you're suppose to be able to
ensure that your resource factory registrations will be taken into
account. I'll try to ask about these issues when I get a chance to talk
with them next week...
