Summary:

Abstract, Scope, and Introduction do not accurately reflect the content of the
document, which is not simply a registration.

Major issues:

The Abstract and sections 1 & 2 (Scope and Introduction) indicate that this
document is simply an IANA registration of an S-NAPTR Application Service Tag.
However, section 3 is quite clearly new protocol, some of which changes how RFC
5222 implementations should operate if used in a particular context, and
section 4 lays out the backward compatibility of this new protocol with legacy
RFC 5222 implementations. There is the implication that the NENA i3 documents
will actually be the home of that protocol, but the current i3 document
referenced here does not do so, making this document the canonical statement of
the protocol operations necessary to implement the i3 architecture. That
doesn't seem appropriate for an Informational document that purports to simply
be a registration.

At the very least, the Abstract, Scope, and Intro would need to be updated to
reflect the actual contents of the document. I think things would be better
served by making this a Proposed Standard document so that it gets the
appropriate level of review. I understand from the Shepherd writeup that the
ECRIT WG doesn't have the energy to really work on this document. However, this
is a simple enough extension to the LoST protocol that I think it's
unproblematic to have it as an AD-sponsored standards track document.
