Re: [jboss-dev] changes in parsing with xb

Just the fact that there's a bunch of descriptors that we've distributed which don't even conform to the schema really, really sucks.

For one thing, there are lots of XML editors out there which will tell you if you've violated the schema. For another thing, if the violating descriptors still deploy, then maybe the XSD are more strict than they ought to be (I already mentioned one case of this here: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=153482 ). I think that since compatibility with prior versions is a concern, the only logical course of action is to modify the XSD to be more lenient.
