I agree fully that the text is confusing. That's why we've got such a
rat's nest of threads around this. Thomas' draft is trying to make it
better.
I also think you and dean (at least) have been talking past each
other. There is no prohibition in 3261 against a proxy adding more than
one RR value. And there is definitely nothing from the vantage point
of elements on either side that would break if it did so (assuming it
put appropriate values in of course).

robert,
thanks for the pointer. the text is quite confusing though,
because in
the list point 8 is OPTIONAL and also the first paragraph on point 8
says that a proxy MAY choose to do some re-writing and then the next
paragraph says that a proxy MUST do rewriting and change uri scheme
depending on transport.
anyway, i still don't understand what does it matter to upstream or
downstream elements if proxy is adding more than one r-r header to the
request.
