Re: [AVTCORE] [Technical Errata Reported] RFC3711 (3420)

Using the criteria at 
<http://www.ietf.org/iesg/statement/errata-processing.html> I recommend
putting this into Hold For Document Update.

( I could make an argument for Reject, given the text in 3550 is very 
clear, but a working group can make that decision if 3771 is ever revised).
