No it does not. It does not implement the most basic requirements of
that protocol, which would be to return a response header saying "DAV:
1". See https://www.ietf.org/rfc/rfc2518.txt section 15.1.

We're extremely liberal with that we accept, but it has to at least
marginally follow the protocol specification.

I put the patch shown below to /usr/ports/devel/subversion/files/patch-zz-DAV-robustness.local on my FreeBSD system, and then I reinstalled the port - problem solved. Happy discussions!

Good for you. If you ever get an error saying "Malformed XML in
response," please don't ask us to fix it.
