The intent in my head when working on RFC 8265 & RFC 8266 was to define
the set of rules for a profile and then in each subsection (preparation,
enforcement, comparison) specify each rule to be applied for that
operation, without having them be additive (i.e., don't say in the
enforcement operation than you first do everything in preparation, then
some things in addition). Clearly, this did *not* get translated into
the final text because I failed in my responsibility as a spec author.

I will send proposed text for errata to this list sometime soon.
