<without any hat>

I agree with Nick:

1/ the paragraph identified by Ted can only bring confusion (e.g., when comparing two URI for the same address), so, better remove this kludge from the I-D [1]
2/ getting feedback from transport area is probably required for the URI syntax

In addition and with my AD hat, I am slightly annoyed that the lack of willingness to implement was not detected during the IETF Last Call in 2012.

Regards

-éric

[1] and this will be a real value for the bis document else I do not think that the -bis is really useful

    yip, agreed. This looks like it may be troublesome to implement, with 
    marginal benefit.

    Otherwise the ID update is useful and it would be good to get input from 
    the URI + browser people to see whether they think that it's workable.
