1. Sample instance.xml for Book
Books typically won't have any summary of holdings information and subsequently any specific holdings like MFHD etc. Staying consistent with the design, there will be holdings section defined in "oleHoldings" but wont have an "extentOfOwnership" section.
2. Single-Vol-Serial-IU
Holdings information is recorded in the raw marc format. There is no entry for oleHoldings.
3. Sample instance.xml for Multi Volume Work
