[postgis-devel] Motion: vote for considering SRID <= 0 as "unknown"

Trying to get out of the impass about SRID, I'd like to split
the issue in two:
(1) Considering SRID <= 0 as "unkwnown"
(2) Finding a consensus about how to advertise "unknown"
at the SQL level
I'd like to vote on (1) first.
If we agree, the parsers (all of them) would take any SRID <= 0 as
semantically equivalent to an "unknown SRID", storing NO srid in
the binary representation.
This would mean that no matter what we decide to return from ST_SRID(g)
it will be possible to get in output something different from what was
specified in input.
I'll start with my +1.
