[wildfly-dev] Dropping legacy XSD schemas & its parsers

[Stefano Maestri]

Hi all,

I've probably missed the final decision about that. I've worked on 2
issues last week:

- WFLY-4566 Remove support for jboss-as-datasources_1_0.xsd
- WFLY-4568 Remove support for jboss-as-resource-adapters_1_0.xsd

removing very old xsds. I have a lot of tests failing because we still
support 7.x xsds.
I would suggest to reopen this discussion and evaluate if and when we
are de-supporting them.

I'm sorry if a decision was already taken and I've missed or
misunderstood that one

regards
S.
