Say I have a catalog HelpCatalog, with a bunch of documents that have unique IDs. I want to be able to do something like HelpCatalog/by-id/SomeUniqueID and have it return the document SomeUniqueID.

Do Catalogs support any sort of Direct Traversal like this?

No but it's not a bad idea.

Or am I going to have to do it myself with a mixin class?

You could allways submit a patch. ;) Note that ZTopics, in a way, does this genericly, it executes canned queries based on traversal, it might need to be fondled a bit to get it to do exactly this however. -Michel
