I don't know DAV internals but considering the fact it works over
HTTP, at worst one can add

X-Subversion-ErrorMsg: <message goes here>

to the HTTP headers. Moreover, at the first glance, DAV specifies
'responsedescription' element so one can write

HTTP/1.1 207 Multi-Status
Content-Type: text/xml; charset="utf-8"
Content-Length: xxxx

<?xml version="1.0" encoding="utf-8" ?>
<d:multistatus xmlns:d="DAV:">
<d:response>
      <d:href>http://www.foo.bar/directory/element</d:href>
      <d:status>HTTP/1.1 412 Precondition Failed</d:status>
      <d:responsedescription>Subversion pre-commit hook failed
with message: comits to the stable branch must mention bug
numbers.</d:responsedescription>
 </d:response>
 </d:multistatus>

(as i read http://www.ietf.org/rfc/rfc2518.txt, seems that
responsedescription can be placed both within response and
sideways to it, I do not know which solution is preferable).
