MODS documentation does not explain an expected syntax for the examples. This would be very helpful. What is the expected syntax for typeURI?

manuscript

Definition
A resource that is written in handwriting or typescript.
Application
This attribute is used as manuscript="yes" when a collection contains manuscripts and is considered generally to be manuscript in nature, and for individual manuscripts.

A collection is not the same thing as a DC collection, so what does the XSD say?

Where does the OLAC grene terms map to this list?
