Yunhao,

I still think we have to be careful here not to end up testing
every x.509 failure mode, so in your list below I'd change to:

3: Handling error response(s) to a revocation request
4: Handling error response(s) to a registration request
5: Unacceptable signature

Sorry to go on about this, but there is a rats-nest awaiting
us if we not careful!

Stephen.
