As I've said before, what really bothers me here is that there are
mandatory actions specified if the sub-TLV is malformed...but this
check is optional.  The real source of my issue is that §3.1 includes
the list of conditions to consider the sub-TLV malformed, and it
includes this one:

  o  It can be determined according to the procedures below
     (Section 3.1.1) that the IP address in the sub-TLV's address
     subfield does not belong to the Autonomous System (AS) that
     originated the route that contains the attribute.

I read this text as expecting §3.1.1 to be used.

NEW (aligning with §12 too)>

  o  It can be determined that the IP address in the sub-TLV's address
     subfield does not belong to the Autonomous System (AS) that originated
     the route that contains the attribute.  Section 3.1.1 describes an
     optional procedure.

Done. (I added “… to make this determination” at the end.)
