[Zope] tree tag and the URL attribute

Hi Florian!

You use "urlparam" for adding a query string to the created links. 
Unfortunately, you won't be able to add a _dynamic_ query string, since you 
pass "urlparam" as a string literal.

Doing this would require something like "urlparam_expr" instead of a plain 
(string literal) "urlparam" parameter, that would be rendered before 
inclusion. The tree tag doesn't support this for the time being, but there 
are numerous patches (and for quite a long time, too - I hope one of them 
will make it into 2.5). Check the collector (as soon as it's working again) 
and the mailing list archives for "urlparam_expr".

hth,
Danny

P.S.: Note that my own patch won't work (as it is) on Zope 2.4x...
