Re: [6tisch] removing the 'e'

If Kris is correct, and compliance with the 15.4 rollup would cause code changes to existing 4e code, then I don't think it's a good idea to remove the 'e' -- if existing 4e code would be interoperable with 15.4 rollup, then I guess referencing the rollup (for posterity) would be a good idea.

I like the IETF approach better, but I don't think that we have much choice.
If the roll-up from 15.4e to  15.4-2015 were just corrections of real problems it would be a no-brainer.
Unfortunately, there are numerous cases where IEEE members with "good ideas"
have pushed for changes that have little or no practical value, but do require a re-write of existing code, and mandate non-interoperability between the existing 15.4e and the forthcoming 15.4-2015.

Subir noted that at the IETF we normally have reference on particular versions, and a change in an RFC is a new RFC thus a new reference, and the IEEE form of reference may create an issue with IETF practice. The chairs will need to validate this before proceeding.
