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. -Toke
