* 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. |
