It's not *when* the field should be set to 0 that is unclear, but rather
that this changes the semantics so that the TLV no longer encodes a
prefix, but rather turns into a wildcard request.

Adding some text to that effect could be done in section 4.1.3, for
instance. I.e. instead of writing:

   o  AE 0: wildcard address.  The value is 0 octets long.

one could write something along the lines of:

   o  AE 0: wildcard address. The value is 0 octets long. When this is
   set, the TLV does not encode a prefix, but rather contains a wildcard
   request.



Not sure if this is the right place to do it, or if this should be done
in section 2 or 3 instead (where the description is more conceptual).
But I think it was the term 'wildcard address' with no further
explanation that sent me down the wrong track.
