Web Identity 1.0 -- Draft Spec

https://web-payments.org/specs/source/web-identity/

This is some work going on in the web payments community group.

Still a very early draft, but it may be interesting to compare how the
payments group does identity compared with this groups efforts.

Bear in mind that there's quite a bit of industry backing behind payments,
including active participation from Mozilla, so this set of specs may end
up winning the race to become w3c RECs.
