At least my understanding was that "Key Type" would be a single 
value (URI), and the things currently under Usage (ChallengeFormat,
Encoding, CheckDigit, ...) would all be key attributes. So I'd 
propose just renaming the KeyAlgorithm attribute (in Key) to 
KeyType (we did debate whether this should be called "Key Algorithm",
"Key Type", "Key Class" or something else, and settled on "Key Type").

Splitting the Key Attributes to two places is OK, but for consistency,
they probably should be named AlgorithmAttributes (instead of
AlgorithmParameters -- I think we did discuss whether these should be 
called "Key Attributes" or "Key Parameters" or something else),
and "PolicyAttributes".

But otherwise this looks pretty good!
