Thank you, Jon.

I agree that the meaning/intent of SPKI would be *much* clearer if the
word "certificate" was replaced by "assertion".

I also agree that "attribute" is a better name for a field in an SPKI
assertion than "auth", but there may be some who feel that attribute
sounds too X.509-like :-).
