Subject: RE: Diameter EAP contradicts RFC 3588

Hi,

I think Glen is right here. RFC 3588 says "MUST", and the
"MAY" in current text is IMHO an accident (I don't think
anyone ever proposed that there would be valid reasons
not to advertise the support. Of course, an implementation
may have a switch for disabling EAP, but then it's no
longer supported).

Thus, I'd propose the following RFC-Editor note:

-----------
Section 2.1, 1st paragraph:
OLD:

  Diameter nodes conforming to this specification MAY advertise ...

NEW:

  Diameter nodes conforming to this specification MUST advertise ...
                                                  ^^^^
------------

Given that this sounds like a technical change, the RFC
editor probably wants this from the ADs..

Best regards,
Pasi
