You can't do that.

I have no idea what kind of code tweaking you're referring to here, but it
will invariably be wrong.

Yes, of course.

mod_dav_svn is *NOT* a general WebDAV provider. It has _just_enough_
functionality to support the SVN client, but no more. You can browse a
mod_dav_svn-based repository using a DAV client, but you cannot make any
changes (e.g. MKCOL, PUT, PROPPATCH, etc). To make a change, you must go
through a specific sequence of operations, following one of the models in
the DeltaV RFC.

Some of the DAV stuff is discussed in www/webdav-usage.html. That page is a
bit out of date, but I should be completing it next week.

Not in the sense that you're thinking of. Our test suite covers SVN
operations. Not DAV operations.

Note that even the 500 that was returned when you tried the MKCOL is a
deficiency in mod_dav_svn's support as a general DAV provider. It should
have returned a 403 or a 409.

The next version of Subversion (e.g. 2.0) will be a true WebDAV provider.
For now, we use and implement just enough of the protocol to satisfy our
network needs. The parts that we *do* implement are conformant, but we don't
implement "enough" to be a general server.
