LC: Clarify expectation of deleted-nodes property of xforms-delete

In Section 4.4.6, the xforms-delete event is discussed.

The deleted-nodes property states that the deleted "nodes are no longer 
referenced by their parents."  It is strongly implied but not stated that 
the detachment is only one way, i.e. that the nodes still reference their 
parents.

It should be clarified that it is possible to traverse upward to the 
former ancestors of the deleted nodes. 

This should also be normatively stated in the section on the delete action 
(Section 9.3.6, bullet point 4).  Currently that text simply says the 
nodes are deleted but it leaves open to interpretation what deleted 
actually means. 

It should say that the nodes are detached from their parents and queued 
for destruction immediately before deferred update behavior.

Finally, the behavior of properly destroying all 'deleted' nodes before 
deferred update behavior occurs should be mentioned at the beginning of 
Section 10 on XForms actions.
