[BA] That works for me.

[BA] You are right that a number of method specifications are deficient in the
internationalization area. However, I don't think that's an issue that an
ABFAB applicability statement can solve. Sam's proposed approach seems like
the only feasible one.

[BA] I totally agree.

[BA] Yes, but at least the method-specific identities and passwords are opaque
to the EAP core implementation and the AAA protocol.

[BA] Exactly. It's just an applicability statement, not a prescription for
world peace :)
