[Zope] Variable sort and multiple sort in dtml-in

On 02 July 2000, Adam Karpierz, posted a patch that would allow an expression for the sort specification for the dtml-in tag. Did that patch, or something like it, ever find its way into the Zope core? I also seem to remember some discussion of sorting on multiple items (but can't find any trace of it in the archives). For example, in an employee directory, sort on employee name within department. Anyone know how? I'm trying to provide user-specified sorting on the records I pull from a SQL database. When the user specifies sorting on Department, I assume he wants the records order by Name within each department, but I can't see how to do that with ZSQL or dtml-in. -- Loren
