It does, but only as long as you do not use it as part of
a larger macro body. This is because the standard predefined
ZPT macros are initialized only once when the rendering of the
outer macro starts and remain then unchanged across all macro
expansions.

I think this is a severe limitation and tries to remove the restriction.
But, it turned out to be too effort intensive.

Always do this, as it is more (but not yet completely) resilient 
with respect to nested macro definitions.
