+        The entity-mappings element is the root element of a mapping
+        file. It contains the following four types of elements:
+
+        1. The persistence-unit-metadata element contains metadata
+        for the entire persistence unit. It is undefined if this element
+        occurs in multiple mapping files within the same persistence unit.
+        
+        2. The package, schema, catalog and access elements apply to all of
+        the entity, mapped-superclass and embeddable elements defined in
+        the same file in which they occur.
+
+        3. The sequence-generator, table-generator, converter, named-query,
+        named-native-query, named-stored-procedure-query, and 
+        sql-result-set-mapping elements are global to the persistence
+        unit. It is undefined to have more than one sequence-generator
+        or table-generator of the same name in the same or different
+        mapping files in a persistence unit. It is undefined to have
+        more than one named-query, named-native-query, sql-result-set-mapping,
+        or named-stored-procedure-query of the same name in the same 
+        or different mapping files in a persistence unit.  It is also
+        undefined to have more than one converter for the same target
+        type in the same or different mapping files in a persistence unit.
+
+        4. The entity, mapped-superclass and embeddable elements each define
+        the mapping information for a managed persistent class. The mapping
+        information contained in these elements may be complete or it may
+        be partial.
