A couple of small clarification/corrections:

   From: Tim Ellison [mailto:Tim_Ellison@uk.ibm.com]

   By checking out a collection you make the collection resource (including
   its internal members == "bindings") mutable.  This means to rename /a/b
   /a/c then the collection /a/ must be mutable, but /a/b and /a/c can be
   immutable versions.

Tim was using "version" in an informal way here.  /a/b and /a/c are
checked-in (and therefore immutable) version-controlled resources, but
they aren't versions in the formal DeltaV sense of the word.

   So if you PROPFIND depth 1 on a version of a collection you will discover
   the internal members are bound to version history resources.

Actually, a collection version is not itself a collection
(it's state is defined by its DAV:version-controlled-binding-set).
We did at one time have the internal members of a collection version
bindings to version-history resources, but that information was
moved to the DAV:version-controlled-binding set property.
So you'd just ask for a PROPFIND;Depth=0 for the

   Indeed, if
   you check out a version of a collection you will get a working collection
   whose internal members are bindings to version history resources.

That is correct.
