Unless I'm totally, hugely mistaken, MARC doesn't say anything about holdings data, right? If I want to facet on that, would it make more sense to add holdings data to the MARC XML data, or keep separate xml files for holdings that reference the item data?
As others have said, you can get *some* holding data in a marcxml file, but nothing that will help you. Especially the holding data could change at a moments notice. You will have to get access to your holdings data some other way on a real-time (or 15 - 30 minute) delay.
