The ResourceSet calls URIConverter.normalize on each URI before comparing them.
If you want to add additional logic to remove ".", "..", or empty segments, you
can create a derived URIConverterImpl, override normalize to do this extra
processing, and set that converter to be the converter for your resource set.
I'm considering whether I should do this kind of processing in
XSDUtil.resolveSchemaLocation so that the schemaLocation URI is "untwisted"
before it's passed on to the resource set. But I also kind of wonder if this is
this a "real" problem or a contrived one? It looks kind of contrived. (I'll
also ask Dave about a method on URI that would collapse the segments.)

Ed,
Thanks for the suggestion. I would go ahead and extend URIConverterImpl to
accommodate my requirements.
Thanks again for your help.
