That is a PROPFIND (Depth:0) for the DAV:resourcetype property.
You can use the svn_ra_dav__get_one_prop() function to fetch it. If the
PROPFIND fails with a 404, then you have svn_node_none. If the resulting
property looks like:
<D:resourcetype>
<D:collection/>
</D:resourcetype>
Then it is a collection (directory; svn_node_dir). Otherwise, it is a
regular resource (svn_node_file).
The harder part is parsing the resourcetype property. "Proper" parsing means
treating it as an XML property and looking for the DAV:collection element in
there. To do that, however, means that get_one_prop() can't be used. I think
there may be some Neon functions for parsing XML properties; we'd need to
look. That would probably be the best approach. (an alternative is to use
apr_xml_* parsing functions on the returned string; get back a DOM-like
thing, and look for the element).
