[jboss-as7-dev] Automagic Interfaces

[Heiko Braun]

Not sure if we are on the page wrt to this discussion.
(you lost me somewhere) but here are my thoughts about the value type descriptions
and automagic interfaces:

Instead of using the VALUE_TYPE descriptions to get to know the inner structure of a complex attribute,
we could aim for a more simple approach: turn complex attributes into sub resources.

This is not possible straight away and has certain implications:

Sub resources need to be addressable

Consider the "jsp-configuration" of subsystem web for instance.
it's not addressable per se, but it easily can be made addressable:

/subsystem=web/config=jsp:read-resource
/subsystem=web/config=jsp:read-attribute(name=development)

What do we gain?  implicit operations for a the sub resource:
(add, remove, read/write-arribute, etc)

With this we are much closer to automagic interfaces,
then the burden parse & analyze some half-baked description of the structures at hand.

Why "half-baked"? Well, IMO the current description of types and constraints are straight forward 
and easy to understand, but far from be descriptive enough to automagically generate interfaces.

It's still very hard to generate human interfaces from proper xml schema descriptions
and the DMR descriptions don't cover the detail and descriptiveness of xml schema yet.
And in my opinion the shouldn't.  

We better stick to our simple & straight forward mantra
and improve/refactor the current model descriptions like described above before puling the sledgehammer.
