Re: [savi] AD review of draft-ietf-savi-framework

Yes, marcelo is right.
I rememer in the round of WG chair review, it was discussed,
so I think the text below in the curren verison already reflects the 
Marcelo's meaning.

"is to minimize the complexity of the
common case: many link deployments today either ...... or,
equivalently from the perspective of the SAVI method, separate IP address 
assignment
methods into different IP address prefixes. "

thanks，

The difficult case here is when different methods are used to assign
addresses _from the same prefix_
This case is complicated because different methods can assign the same
address and SAVI needs to be able to determine which is the winning method.
So, while i agree with you that it is fairly common the case where
multiple address assignment methods are used in a given link, i believe
that the case where multiple address assignement methods assign
addresses from the same prefix is much less common.

I guess we need to make the distinction clearer in the document.
