I believe what is trying to be explained is that ZPT provides a certain
sequence for attribute *processing*, which begins *after* the template
is parsed (like unordered keyword arguments in Python). How they are
ordered in the source file is irrelevant, but by ordering them in the
precise way they will be processed is recommended to aid in the
understanding of what will happen.

If you do see a concrete example of how and where this occurs that
coincides with a breach from the XML spec, please post this to the list
for us to see, so that the proper avenues of discussion, hacking, and
problem resolution can be made. ZPT is nowhere near complete, and will
surely tighten up with time.

Eron
