There are two issues here, and it is important to realise they are
orthogonal and can be decided separately.

1. Do the keywords take the form of (a) ...!KEYWORD!... or (b)
...!foo.example.KEYWORD!... .

2. What set of keywords (POSTED/SEEN/MATCH/MISMATCH/WHATEVER) do we
provide?

Ad #1, I opriginally proposed ...!KEYWORD!..., and it was accepted (hence
that is the current official WG position). The reason was that if you
allow

...!injector.example.com.POSTED!tail-entry

then a site that peers with injector.example.com will not know that it is
not supposed to relay the article back to injector.example.com. OTOH, it
does not matter with

...!news.example.com.MISMATCH!bogus.example.com!...

because you are not supposed to look at <diagnostic/source-identity>s when
deciding which peers to relay to. Note that there is some existing
practice with style (b) with both MISMATCH and POSTED.

Hence my proposed 2nd alternative used style (b) for MISMATCH et al, but
still used style <a) for POSTED.

Ad #2, POSTED is presumably non-controversial, as it MISMATCH. There seems
some merit in SEEN (so that all <diagnostic/source-identity>s are
immediately recognizable as such). MATCH is just for the sake of
completeness; it is redundant and would be discouraged in USEPRO; if the
WG wants to omit it, I have no problem.

Essentially, you are supporting style (b), but maybe not for POSTED.
