I was trying not to assume any particular implementation and as far as the
spec goes simply attempting to be consistent with following the rules of what
to do when modifying route tables.

Steve,
With regard to your statement:

I don't really understand how that could happen unless an expander has 
to rearrange its hardware route table in the process of changing the 
zone group for one or more of its entries.  Are you asserting that that 
may be required - perhaps hardware dependent, or am I missing something 
in my fundamental understanding of how this works?  In any case, I'm 
willing to concede the point.  I'm OK with your suggestion.
Greg
