Doesn't the receiver also have to match on some other things e.g.

- that the Purge comes from the same guy that supplied the cached 
  information: match on Source IP Address or Source NBMA Address

- that the QoS matches what was cached.

- what about authentication? Is that used on Purges?

- what about NBMA Subnetwork ID? Nowhere is it mentioned that this
  is or is not allowed in a Purge: presumably it does need to be
  there in the Purge if an implementation is using it in Request/Reply 
  packets. If it's there, it needs to be checked.

I thought things were actually more correct, if a little less clear, 
before you added this paragraph!
