4.4 - operational context

4.4; e.g. 4.4.1 appear to lack the reason/context for why this operational environment is to have certain properties. Or what to measure these properties against.

So I would set the stage by clarifying that this is to get sufficient (e.g. risk, context base) control over the usage of the private key material, the (auxilary) data making it into the signed portion of the certificate and they key services needed for the CA/RA, etc activities.

And then peg things, e.g. physical security, to that.
