> Say we have a composite operation with 2 steps:
> 1) /extension=org.jboss.as.messaging:add
> 2) /subsystem=messaging:add
> This will fail:
> Failed to execute batch: JBAS014739: No handler for add at address
> [("subsystem" => "messaging")] 
> This fails because at the time of validation the /subsystem=messaging:add is not valid.
> To illustrate, the execution order is
> Validate 1-2
> 1
> 2
> A possible solution is to convert this to the following:
> V1
> 1
> V2 (works now because 1 has registered the subsystem API)
> 2
> I think that should work but it's a very complex area, particularly in a managed domain, so it's not at all certain this would prove feasible.
