I would like to add that at the London IETF meeting the majority of the 
discussion on this draft was on this issue (i.e., whether to split the 
source address selection document into two documents).  At the end of the 
discussion, there was a general consensus to not split the document as 
doing so would harm interoperability.  This was captured in the minutes for 
the meeting.
