We recently realized that RFC3648 forbids servers to allow ORDERPATCH to 
turn a previously unordered collection into an ordered collection (see 

Of course that's not what it was *supposed* to do. On an unordered 
collection, setting the DAV:ordering-type so that the collection becomes 
ordered of course is one of the use cases for it.

I added the issue as 
and propose to resolve it my changing the description of the 
precondition to:

"(DAV:collection-must-be-ordered): If the request is applied to an 
unordered collection, and if the request body contains an order-member 
element, it MUST also specify an ordering-type element, turning the 
previously unordered collection into an ordered collection (see also 
Section 6.1)."

(needless to say this is what SAP's KM has been implementing for years...).
