The semantics that let you use VERSION-CONTROL to "restore" any resource 
from its version-history are defined in section 6.7.
Section 14.8 is just the extended semantics of VERSION-CONTROL when 
restoring version-controlled-collections.

You cannot use BIND to "restore" a version history, because the child of a 
version-controlled-folder is a version-controlled-resource, not a 
version-history, whereas BIND is defined to make the specified resource a 
child of the specified collection.

Cheers,
Geoff
