I'd suggest using a different namespace than www.postgresql.org, just to be sure it won't conflict with some system we use in the future. Perhaps http://schemas.postgresql.org/<whatever>? It doesn't actually need to exist until we want to put anything there, but it mustn't conflict with anything else. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
