[jboss-as7-dev] Validation of XML Parsers / Schemas

[Anil Saldhana]

IMO schema validation is needed when:
a) users want to enable it to debug an issue.
b) testsuite needs to validate schemas.

In both these instances, the Jaxp Validation API is sufficient if the 
schema files are known. Would it be useful to just enable jaxp 
validation (on demand) before the subsystem parsing kicks in?
