Updated version of NSIS extensibility draft submitted (draft-ietf-nsis-ext-01)

Hi.

I have updated the NSIS extensibility draft to take account of the
comments from Martin and Hannes, plus making sure that it is clear what
the IANA/IETF requirements ae for various types of extensions as well as
providing guidelines.  This last exercise is (I hope) in line with
Magnus' comments at the last IETF.
http://www.ietf.org/internet-drafts/draft-ietf-nsis-ext-01.txt

Otherwise, the major change is to greatly extend the commentary on
packet interception mechanism extensions.

Please take a look:  I think it is probably ready for WGLC, but if
anybody has immediate concerns I can cycle another set of changes
through before the draft deadline.

Unfortunately I will not be at the nsis meeting (scheduled for Thursday)
in San Francisco as I have to leave on Wednesday.

Regards,
Elwyn
