One thing which is not disclosed in documentation and which I cannot find anywhere is how to define dependencies in my subsystem or extension -  practically how to say jboss, that my extension depends on other subsystems. In my example I get datasource name and topic configured for my subsystem as simple string attributes (can be I had to use something else - dunno - so far string). But how can I ensure, that "datasources" and "messaging" subsystems are started and have already deployed their stuff  (datasources and topics) before start of my subsystem is called? As I said this topic is not documented well and unfortunatelly I could not find much info on it. Javadoc is also mostly absent. Many thanks for your help in advance.
