[OAI-implementers] namespaces not resolving

In defense of the LoC/MARC-XML folks, as late as the March 2003 draft 
of AWWW [1] there was no clear recommendation about namespace documents, 
and MARC21/slim was released way back in 2002. However, since current best 
practices have settled around the current AWWW recommendations it would 
be nice if the LoC/MARC-XML folks made the namespace URI resolve... anyone 
listening?

This also serves as a wake-up that we should make the OAI namespace URIs
resolve too (none of which give anything useful at present):

http://www.openarchives.org/OAI/2.0/oai-identifier
http://www.openarchives.org/OAI/2.0/rights/
http://www.openarchives.org/OAI/2.0/branding/
http://www.openarchives.org/OAI/2.0/gateway/
http://www.openarchives.org/OAI/2.0/friends/
http://www.openarchives.org/OAI/2.0/provenance
http://www.openarchives.org/OAI/2.0/static-repository

I wish we'd been consistent about trailing slash or not...

Cheers.
