A workaround is needed for servers which provide no correct resource type.

[Tobias Schlauch]

Here an example server which causes the problem: http://dav.mentor.ieee.org:80/

If the property is not available, check the leading "/" (available -> collection, not available resource).

A closer look at the problem showed:
- In general, the server correctly uses the resourcetype property.
- Only the root collection causes the problem: The property has not been correctly selected from the property response!

The source of the problem is that the depth header for PROP* requests is not correctly interpreted. depth=0 and depth=1 return the same: requested source and the children.
