COMMENT:
----------------------------------------------------------------------

I'm not sure whether this should really be a discuss ... I raised a similar
concern on the OSPF document as part of a discuss, and presume consistency is
helpful.

4.1.  Application Identifier Bit Mask

  UDABM Length: Indicates the length in octets (0-8) of the
       User Defined Application Identifier Bit Mask. The length SHOULD
       be the minimum required to send all bits which are set.

   User Defined Application Identifier Bits have no relationship to
   Standard Application Identifier Bits and are not managed by IANA or
   any other standards body.  It is recommended that bits are used
   starting with Bit 0 so as to minimize the number of octets required
   to advertise all UDAs.

In section 4.1, I think that the document should also add the sentence (taken
from the previous paragraph) "Bits that are not transmitted MUST be treated as
if they are set to 0 on receipt."  Note, that I also think that this behaviour
is implicitly required from the description of UDABM Length.

Regards,
Rob
