Re: [Roll] I-D Action: draft-ietf-roll-nsa-extension-04.txt

Hello,

I have just submitted a new version of draft-ietf-roll-nsa-extension
(draft-ietf-roll-nsa-extension-04) which follows the general recommendation
from all the reviewers of our draft: Explicitly specify the OFs to use with
the proposed PS NSA extension.
While there were examples in the previous version of how an OF would
roughly work, in this newer version there is an explicit description.

We wanted to specify OFs which basically work like MRHOF does for the
(normal) preferred parent, but which additionally does alternative parent
selection.
To minimize the extent of the description, we have chosen to "extend" MRHOF
by describing what is done the same and what is changed compared to MRHOF.
We take each section in the description of MRHOF and we describe the
changes or lack thereof.

I'm not sure if this method of extending existing behavior is helpful, so I
would really appreciate some feedback on this.

Kind regards,
Aris
