Hey,

there's one thing I don't really understand from this draft.

Is this useful for DNS at all, or is this targeted at DNS-SD only?

I think this needs some explaining and perhaps a clear cut is needed.
Although it's not mentioned anywhere in the document, the draft makes
much more sense to me, if it would clearly state, this should be only
used in DNS-SD sessions.

Cheers,

> Abstract:
>   The EDNS(0) Extension Mechanism for DNS is explicitly defined to only
>   have "per-message" semantics.  This document defines a new Session
>   Signaling Opcode used to communicate persistent "per-session"
>   operations, expressed using type-length-value (TLV) syntax, and
>   defines an initial set of TLVs used to manage session timeouts and
>   termination.
