*ISIVTCollection* collections exist because *Python was not in Softimage since the very beginning*, so a few of the SDK command implementations used these so-called "output arguments" feature (since a big chunk of the core commands are written in VBScript, which supports it.) The special collection object was a way of getting them to be accessible automatically without having to go back and add new commands.
>>* Either way, I don't think the new SDK docs really show what arguments are the ones returned * Perhaps not clearly, but they *do* show. For example: http://download.autodesk.com/global/docs/softimage2013/en_us/sdkguide/si_cmds/PickElement.html Note how in the 2nd paragraph they mention output arguments, then in the Parameters list, for "*PickedElement*", "*ButtonPressed*" and "* ModifierPressed*" the Description of the parameter reads *"Returns the..."*. That's how you know it's an *output argument*; because it's trying to return something. The Parameter name for the output argument is the key for the ISIVTCollection returned, so in this it might be something like * Application.PickElement(...)("PickedElement")* for example.
