[jboss-as7-dev] update messaging subsystem config to 1.2

Hi, I am working on a JIRA issue to add missing configuration parameters to messaging resources[1] I did a quick patch to unblock the performance teams but I am revisiting it to fix it properly[2]. As I am changing the XSD schema, I need to bump up its version. My changes are small (I'm just adding elements) but I wonder what the policy to manage schema changes is. * should I be able to read any previous configuration version? or only the last 2? * if I am reading an old configuration version, should I persist it at the same old version or the latest version? I looked at ejb3 subsystem to see how configuration schemas are handled. Is it a good candidate to copy? thanks, jeff [1] https://issues.jboss.org/browse/AS7-4330 [2] https://github.com/jmesnil/jboss-as/commit/2f4389a10fe61bd054a5e4729ae8c6... -- Jeff Mesnil JBoss, a division of Red Hat http://jmesnil.net/
