That's not how I read it.  I understood that paragraph as saying that a  
server could call something a collection (using the resourcetype property)  
but have it be non-WebDAV-compliant resources.  In fact "not be WebDAV  
compliant" is in the first sentence.  So that's why I asked if anybody had  
implemented non-WebDAV-compliant resources that still had the  
DAV:collection element in the DAV:resourcetype property.  I can imagine  
how one might use this -- for example, it might show up in its parent as a  
collection yet not itself support direct PROPFIND requests -- but I am  
unaware of any implementations.

I also figured that shared locks were implemented already although I'm not  
sure they satisfy the 2x2 test requirement.  But what about non-write  
locks?  Has anybody implemented locks that aren't write locks and don't  
advertise themselves as such?

The way this impacts the document is that sections 6 and 7 could be merged  
if there are effectively only write locks.  Section 6 discusses locks,  
section 7 discusses specifically write locks.
