[pcp] section 8

[Tina TSOU <[e-mail]>]

Hi,
In section 8, it reads:
  "It is REQUIRED that the PCP-controlled device assign the same
   external IP address to PCP-created explicit dynamic mappings and to
   implicit dynamic mappings for a given Internal Host.  In the absence
   of a PCP option indicating otherwise, it is REQUIRED that PCP-created
   explicit dynamic mappings be assigned the same external IP address."
It is not consistent with what we have discussed in the mailing list below. And it is a bit ambiguous in reading.

How about changing the second sentence from on of the 4 candidates as below?

Alternative 1:
PCP client should request same external IP address for an application if there is already any existing explicit mapping for that application.

Alternative 2:
PCP client should request the same external IP address if there are existing explict mappings, unless there is explicit reasons of not doing so, e.g. http://tools.ietf.org/html/draft-penno-pcp-zones-00

Alternative 3:
It is indicated by the PCP client that PCP-created explicit dynamic mappings be assigned the same external IP address, unless there are explicit reasons of not doing so, e.g. http://tools.ietf.org/html/draft-penno-pcp-zones-00"

Alternative 4:
It is indicated by the PCP client that PCP-created explicit dynamic mappings be assigned the same external IP address, unless a PCP option indicates different external IP address
