This is entirely unrelated to Kate's request.=20

Based on what I can infer from Kate's request, she is proposing a URN suppo=
rting an open but proprietary scheme for managing key derivations in a card=
 issuance scheme which is not intended to be, or advertised as, compliant w=
ith GlobalPlatform specifications.

It might make sense to ask Kate to remove the reference to GlobalPlatform k=
eys in the template as:=20

1. It doesn't seem to be relevant to the technical intent of the registrati=
on;=20
2. It is not correct - GlobalPlatform cards supporting the latest specifica=
tions (GlobalPlatform Card Specification, Amendment N, v1.0) support AAD of=
 16..512 bytes for key derivation.
3. It avoids any confusion about whether this scheme is in any way associat=
ed with GlobalPlatform, which it is not.
