Re: Draft response to MFA liaison

["Andrew G. Malis" <[e-mail]>]

Adrian,

Thanks for your comments so far.  Regarding the references to drafts,
those of us in the MFA have been hoping that many of these will be
reaching the RFC editor's queue relatively soon.  If they get held up,
we'll have to decide on a case-by-case basis how important that draft
(and the functionality it supports) is to the specification, and
whether we we would be better to remove the reference or hold up the
work. Perhaps we could move the functionality in the drafts to a later
revision of the spec. We'll be discussing this at our next meeting.

This issue is a particular sore spot.  I'm very mystified in
particular as to what's been holding up the BFD specs.  Everyone is
implementing the expired drafts, but the limbo that the drafts are in
is affecting work both in the IETF and outside.

Cheers,
Andy
