Hi Michael


quick recap of my problem:
- I need to take xsd files as input
- I want to make sure the xsd files are valid before I start processing.
	- if they are not valid it would be nice to get an error message like you could generate from a SAXParseException.
- My tool has to work even if it is offline or w3.org is not available.

If I understand your proposal, you are saying the SchemaFactory.newInstance() is hard code to know about XMLSchema validation. Because the API has you pass a string "http://www.w3.org/2001/XMLSchema" instead of an enumerated value. I assumed the factory had no explicit knowledge about XMLSchema, so I was doing a lot of work to create Sources for XMLSchema.xsd, creating a validator for XMLSchema, ...

I should have time this week end to give this a try.
