I first thought so, too, but you can just as well take the same
definition as OpenPGP uses as GnuPG's native interface and document it
in doc/DETAILS.  If you squint your eyes the right way, the
differences are merely syntactical.  That means that gpgsm can easily
dump OpenPGP like subpackets for notation data, if so is desired.

My main concern here is consistency: I should be able to read and
write exactly the same notation data.  If I can read a notation data,
I want to be able to write it, essentially making a 1:1 copy.

Reading and writing subpackets (notation data, policy URLs) should be
very similar.  I think that is just a sanity requirement.  Currently,
this is not met.  David said the OpenPGP raw format is the one to go
for.  You seem to say the NOTATION_* format is the one to go for.  I
will feel better when you both agree on the subject :)
