* Pre- and post-validate macros as they're parsed. Pre-validation

* occurs when the macro has been detected and its arguments parsed.

* Post-validation occurs when all child macros have also been parsed.

* In the ELEMENT case, this is simply the parameters of the macro; in

* the BLOCK case, this is the HEAD, BODY, TAIL and so on.
