[jboss-as7-dev] Description provider duplication example acme-subsystem

[Emanuel Muckenhuber]

Yes, this duplication is intentional. The one used in registerSubModel() 
is the model description of the sub-resource, the other describes the 
'add' operation, which is creating the resource in the end. So in this 
case it's quite likely that the subModel 'attributes' and operation 
'request-parameters' are pretty similar. We are working on additional 
utils which should help to reduce some of the duplications in future. 
Does that answer you question?
