A simple schema to express some elements about a holding (including 'item' or a holding/copy/etc) in an ILS or other library inventory system. Meant to be used wrapped in a DLF di document, or other document where you need to include a package describing an ILS holding.

This schema specifically includes elements that I could not find a good way to express in existing standard metadata packages, such as MFHD or dlf:SimpleAvailability (or any other schema I looked at). It does not for the most part include elements that can be adequately expressed in one of those standard schemas.
