What are the intended use cases for CustomCollectionType vs. UserCollectionType ?

Which one should I use if I want to use my own collection with Hibernate?

This example (http://www.javalobby.org/java/forums/m91832311.html) uses UserCollectionType. But I could not find examples using CustomCollectionType, how can CustomCollectionType be used ?

What are the advantages/disadvantages of using CustomCollectionType vs. UserCollectionType ?
