This is kinda-sorta the territory of tree transformation. 
Conditions that, on the face of it must be in the style langauge
such as:

        if date > 1/1/1999

Can be delegated to an earlier tree transformation that either
establishes a TRUE/FALSE attribute on each element or renames
the elements so that you can trigger different rules.

This is DOM territory since DOM is read/write. As a result
this sort of transformation should be doable from
whatever scripting environment we access DOM from.
