  LPS-17258	WebDAV PROPPATCH does not properly handle locks or multiple custom props
  LPS-1402	Windows WebDAV does not handle files or folders with non-ASCII characters
  LPS-12082	WebDAV does not properly handle <D:lockdiscovery>
  LPS-24916	Webdav lock method does not report infinite lock timeout correctly
  LPS-29438	WebDAV path does not mount properly on XP

Two issues that exist:

1) If WebDAV client has lock for resource and attempts a PROPPATCH, it will fail. Problem is caused by resource being locked but lock not being checked against client's lock uuid.

2) If PROPPATCH is called with multiple custom properties under <D:prop>, it will fail because of unnecessary constraint.

On Vista/Windows 7, this appears to be a problem that shows up as:
"Error 0x80070021: The process cannot access the file because another process has locked a portion of the file."
