the Purpose enum is poorly named

[flihp]

This enum was a quick & dirty way for a KeySpec to pass a configuration value to the ca initialize command. The mechanism is fine, but the name is all wrong. I'm tempted to split all of the CA config off into a new type CaSpec, but it'll need to be linked to the HSM probalby through the label. That fragility can be avoided by just keeping it all in once structure. Probably not worth the effort either.

At the very least, Purpose should be given a better name. Something like CaSection?
