RE: Comments on draft-black-radius-lanedge-00.txt
I support Jari's idea of renaming the group RADEXT to AAAEXT - this I
believe will reflect the true nature of the work and will also help
allay any concerns.

Yes -- though I would probably name RADEXT to AAAEXT and avoid
unnecessary focus to RADIUS only. Not that the name defines what the
group will do, but...

I think its fine to document all the attributes relevant for LANs
together -- but you should then make a distinction of those attributes
that you are now introducing in this document, and those that you just
import from other documents. This would help those readers who know both
documents, would help IANA, and would make it clear what document is
normative wrt to a given attribute.

The definitions appear to have the same contents, given that you refer
to Diameter data type. I think the semantics are also the same. Perhaps
you should just state that this is like the NAS-Filter-Rule AVP -- and
maybe name it NAS-Filter-Rule-Radius or something like that to make it
