Note that random XPath is only supported if the :xpath capability is
supported.  Implementation-wise, if your code handles :xpath, it will
not be more expensive to handle random xpath for partial locking.
(That's what we do in our implementation - we just send the xpath to
our xpath evaluator, and it will return a node set.  Each node in the
node set will be locked.  For a xpath filter in a <get>, we just use
the same xpath evaluator but sends the selected nodes in the
rpc-reply).
