Following on from the work from Paul to add support for stability level based parsing to the subsystems I have been working to make use of Paul's APIs and patterns and add the same for our core management model XML parsing: https://issues.redhat.com/browse/WFCORE-6881 I have just submitted the following draft PR to start to get some CI results and feedback: https://github.com/wildfly/wildfly-core/pull/6134 I am going to start work now on an issue to add some new attributes to the management interfaces at the community stability level. So far I can't add tests for schemas at different stability levels until we have a new schema so will look to add some tests with the follow on work. -- Darran Lofthouse Red Hat <https://www.redhat.com/> darran.lofthouse(a)jboss.com <https://www.redhat.com/>
