Specifically, I'm seeking to get an entry into:


Once we are there, then nobody can bitch at us for using svn: as a property
name prefix :-)

I haven't read them; was unaware of them. Thanks for the pointers! I'll take
a look.

The IANA is the official registry. IETF is mostly about protocols and does
not manage registrations and assignments.

But I'll go read that RFC...

Hmm. Neat. A must read.

That would be nice.

Along similar lines, when we ship a diff up to the server, I will use
application/vnd.svn-svndiff for the MIME type. Probably build recognition
into the server for that and application/svndiff for the eventual point
where we get a formal IANA MIME type registration.

Thanks for the pointers!
