Hi.

No problems with most of this.  Deleted the stuff with agreed actions.

A couple of responses in line to clarify my points...

Right.  Just make it clear they are updates rather than original
definitions - I think I said this rather better in the summary.

Yes. They will stay in the registry but given that 2518 doesn't
explicitly define the registry entries, it would probably be worth
noting the ones that are not updated (and saying this is the case) as
well as thoses that are.

No. I meant in Section 3.  It fits conveniently just after the
Collection definition :-)

True.  How about 'Expressed otherwise, a write lock of either kind
protects any request...'?

Fine by me.

Agreed.

In that case I misunderstood the purpose of the example.  I thought it
was intended to show that some properties didn't come back with allprop.
Maybe the example could be extended to demonstrate this in some way (and
make it clear what didn't come back).
