Sample XML databases?

Question

Are there any notable (large) sample XML databases?

For SQL there are the world and Sakila sample MySQL databases, for example. However a similar Google search for a good XML sample database doesn't give much besides tiny examples at [(not)w3]schools.com which are clearly insufficient for trying out XQuery.
