Subject: [Rats] FW: New Version Notification for draft-tschofenig-rats-psa-token-04.txt

Dear all,

This -04 is a clone of the 1.0.1 release of the PSA Attestation API.

This is now a stable spec that's implemented in TF-M [1].

The idea is to get this published through the independent submissions
stream.

For any question, feel free to contact us.

A short summary of the changes from the previous release:

 * Recommend type byte 0x01 for arm_psa_UEID;
 * Remove erroneous guidance regarding EAT's origination claim -
   it should not be used to find a verification service;
 * Remove normative reference to EAT so that the PSA doc can move
   forward on its own.

Cheers!
