Ok. Let me try to clarify. Hope this helps:

Here's the list of proposed work items. I have
marked the general ones with "GEN", RADIUS-only
ones with "RAD", and RADIUS extensions with some
kind of compatibility need for Diameter with "RAD-COMPAT".

- RADIUS design guidelines [RAD]
- RADIUS/Diameter translation [GEN -- though perhaps best
  treated per application]
- Revised NAI specification [GEN]
- Pre-paid support [RAD-COMPAT]
- SIP support [RAD-COMPAT]
- LAN attributes [GEN]
- MIB update [RAD]

So thats a total of seven work items, three out of
which are generic, two are pure RADIUS, and two are
RADIUS with some compatibility requirements for
Diameter.

I know that the goal is to narrow as much as possible the scope of this working group on RADIUS extensions but reading the first part of charter, I would not understand why such proposal would not be accepted.

There is a proposal for adding better support for LANs and WLANs,
see Farid Adrangi's draft. Its been written for RADIUS only, though
it should presumably work through the usual Diameter NASREQ
translation. Certainly the final RFC, when we get there, should
ensure this. I'd hope that we don't need to duplicate the work
for Diameter NASREQ, and one document would be sufficient. It
certainly seems so at this moment.
