[Roll] New proposed charter

[Ines Robles <[e-mail]>]

Dear all:

We propose the following text to replace the current (much longer) charter [
https://datatracker.ietf.org/wg/roll/charter/], please let us know your
opinion about this.

If you think that other specific topic should be included, please let us
know as well.

Charter proposed might be:

RFC 6550 was published in 2012, and has seen several successful deployments.

Over time, additional issues have come up, including issues in the data
plane of when to use IPinIP headers, and how to compress them, as well as
the standardization of a mixed storing/non-storing mechanism.

The WG is chartered to look at enhancements and maintenance to the RPL
protocol, with the aim of eventually revising and advancing RFC 6550 to
Internet Standard.

Thank you very much,

Michael and Ines.
