[Zope] Iterating over folders with a certain attribute

[Jim Cain]

I want to retrieve the names of all folders that have attribute sequence_id
and then iterate over them, while having them sorted by that attribute. I
can't do something like:

<!--#in "objectValues(['Folder'])" sort=sequence_id-->

because not all folders have this attribute. Am I going to have to build an
array of these objects, and then iterate over them sorted?

Thanks for the help,
Jim
