itemType for list

5.1.2 says "A list datatype must be derived from an atomic or a list
datatype, known as the itemType of the list datatype", which allows
lists of lists but not lists of unions.  I don't understand how it makes
sense to have a list of a list. I also don't understand why you can't
have a list of a union.
