Sorry, but I am lost!
This reference is that of my query, not that of an answer by Ole.

An explanation on this point would be appreciated.
Which sentences of the draft deal with this?

A less "short" list has yet to be made. It should include AFAIK:
- 5th DMR parameter addition (as long as the deletion you suggest below hasn't 
been discussed an approved in the WG)
- ability to disable NAT functionality (which has a normative MUST in the draft)

The specification is AFAIK viable with this 5th parameter, and some may find it 
useful. 
Since it is now a WG matter, individuals who would like to delete it from the 
specification should propose it on the mailing list. 
(FWIW, I have personally no objection to its deletion).

Subject closed, I suppose.
