[wildfly-dev] JAXR backward compat

[Brian Stansberry]

An aside on the general topic of compatibility:

In a managed domain a WildFly 8 domain controller should be able to 
manage an AS 7 slave host controller that is running servers with the 
jaxr subsystem in their profile. So, jaxr can appear in the domain wide 
configuration. However, if the user attempts to use that profile on any 
WildFly 8 servers, it will fail with the message you see.

Same applies to the cmp subsystem.
