[jboss-dev] AS usage of lib/endorsed jars

[Alexey Loubyansky]

XB currently is referencing org.apache.xerces.xs API. There is no 
standard Java API for XSD representation that can be used instead. The 
Xerces' one is the proposal.

BTW, I would like to upgrade Xerces version for the next XB release to, 
e.g. 2.9.1 from 2.7.1. There is a test called XercesBugTestCase in XB 
which fails for 2.7.1. Any objections?

Thanks.
