Awesome. I was aware of TREX, but not of RELAX or RELAX NG. I'd honestly forgotten there were alternatives to W3C XML Schema, which is most likely an unfortunate side effect of having my head down in the SOAP bubbles for too long.
So the question really, as you pointed out, is toolkit support. Anybody know for certain if JAXP allows for pluggable schema languages, or are did Sun standardize on W3C? -Jon Joseph Dane writes: >we already have one of these: > http://www.relaxng.org/ >or maybe you meant "maybe we'll see support for other schema languages >in our WS tools in the future", in which case I wonder the same thing.
