Hi Jukka, Thanks a lot for your comments. We will address issues your raised and submit a new version asap, with a clarification to your last part comments: > - 9.

Thus, MA protocol 4 is DTLS over SCTP." nsis/current/msg08493.html http://www.ietf.org/mail-archive/web Earlier the WG has commented on this, and seems to have agreed on identifying DTLS as a separate MA (thus the ID changed its name as well), which can be used for SCTP and other transport mechanisms in the future: http://www.ietf.org/mail-archive/web//nsis/current/msg08483.html I think this way might make more sense, as it allows a stacked MAs (alike TLS vs TCP). What do you think?
