Hi All,
I am somehow confused about the difference between InheritanceFlags and PropagationFlags.  Pardon me!  English is my second language.

In this context, I would have thought that Inheritance means that a child object derives some qualities from its parent object and that propagation means a parent object transmits some qualities to a child object.  So then, what is the difference between the following two enumerations?

InheritanceFlags
****************
 Member Name        Description
 ------------------        -----------
 None                      The ACE is not inherited by child objects.
 ContainerInherit    The ACE is inherited by child container objects.
 ObjectInherit         The ACE is inherited by child leaf objects.

PropagtionFlags
***************
 Member Name                Description
 ------------------                -----------
 None   
 InheritOnly                     The ACE is propagated to all child objects.
 NoPropagateInherit       The ACE is not propagated to child object.
 
How is it that script writers would say

$inheritance = [System.Security.AccessControl.InheritanceFlags]"ContainerInherit", "ObjectInherit"

and then go on to say

$propagation = [System.Security.AccessControl.PropagationFlags]"None"

Who can explain this in simple terms?
