I have the exact same question. I want to do this for my particular
foo.xml file, but I don't want to register the factory on the entire
".xml" extension. Is there now extended support for this?

Paul,
You can register a factory for *.xml by extending the existing
XMLResourceFactoryImpl and overriding createResource to do something
special for certain special files and call super for the rest.

Paul,
You'd register it only local to your resource set where you have
complete control, not in the global registry that effects everyone,
which would be very rude indeed!
