[jboss-as7-dev] Guidelines for managing management API versions of subsystems

Was just looking at some of the PRs and noticed that after a recent change to Jacorb subsystem [1] we decided to bump the micro version of that subsystem's management API [2]. What are the general guidelines when it comes to bumping the management version of a subsystem? As far as xsd changes are concerned, for EJB3, I've been making sure that the version is bumped whenever there's a semantic change from a previous released version. But I haven't so far touched the management version of the EJB3 subsystem - in fact I had almost forgotten we had that. As a specific example, I introduced a "default-security-domain" management attribute for the EJB3 subsystem recently. Does this warrant a management version bump?
