Summary: This draft is almost ready for publication as a Standard but it
has some issues.

Substantive:

* Section 6.1.2

The draft defines a new option space for the OPT option codes. It is not
clear who allocates and maintains these. Section 7 seems to talk about
what seems to be a well known IANA policy definition ("Expert Review")
but there is no directive to the IANA to create a new options registry
in the IANA considerations section. Please clarify.

Minor:

* Section 5:

This sentence does not read right the way it is written. It is probably
missing a negative.

OLD:

and intermediate gateways...

Propose replacing with

NEW:
Extended Label Types are difficult to use due to the lack of support in
clients and intermediate gateways...


Thanks
