But not during *parsing* of the ZCML:  parsing is supposed to create a
sequence of actions, which, when executed in sequence, make those changes.

Because we check some kinds of errors too early (during parsing:  in
particular, we check the resolvability of "dotted names"), we force some
directives to have "early" effects.
