I always pass arguments explicitly to ZSQL methods. So my ZSQL Method needs
a "parent" param, but it seems that in order to be iterative I need to pass
the current namespace (so the Method can find the ZSQL Methdos next time
round the loop)....so what do I do?

<dtml-var "tree(parent=category_id, <the current namespace>)">

I've tried "_", "PARENTS" and anything else I can think of, but it still
doesn't work....

p.s This leads onto the recurring question (for me at least) of there not
being a way (in the standard_error_message) to fully browse the namespaces
(and their contents) at error time.  Zope is fine when everythings is fine,
but when it( or rather something I do) goes wrong it's hopeless...
