Dear authors,
Thanks for the new version.
I had a quick read on latest version. I find some nits and also some
questions along the way as we meet a scenario when deploying MAP that need
s46 radius attributes.

Section 7.1 should be referring section 3.x not 4.x

1. How is the status of this document? This draft has last called long time
ago, but still not standard yet. What is the reason? Any plans to move
further? As I mentioned we meet requirement when deploying map, we may need
to make a decision if we follow this draft or define a vendor specific one.

2. This draft seems haven't consider conflicts between subscribers. E.g.
EA length conflict between subscribers with in one MAP domain? And EA
length from radius conflict with BNG within same MAP domain?
As this draft enables the capability to maintain MAP rule logic in radius,
conflict mechanisn should be investigated in my POV.

Appreciate your feedback.
Thanks in advance
