How about one spec with two implementation profiles?

WOES-P  MUST implement PKIX key handling.
WOES-R  MUST implement raw key handling.

The reason I think we need both is that the WOES-R mechanism is going to be
much more appropriate for the applications for which self-signed certs are
generally used.

[I really can't see what benefit a self signed cert provides over a raw key
for any application. All you have is proof that the holder of the key
created a self-signed cert.]


So in my application I am going to want a stack that supports certs for the
Internet trust aspects and a stack that supports raw key for the handheld
device aspects. I don't want to implement the raw key in the Internet
request side of things and I definitely don't want to implement the cert
stuff in the handheld device. Mobile phones come with PKIX libraries but
thermocouple driver chips don't .
