+The latest revision of the version 2.0 orm schema is presented below.  Version
+2.0 of the schema must be used if JPA 2.0 elements are specified as XML
+metadata.  Many of the elements in the schema relate to object/relational
+mapping rather than metadata; these elements are discussed in
+<a class="xref" href="jpa_overview_mapping.html" title="Chapter&nbsp;13.&nbsp; Mapping Metadata">Chapter&nbsp;13, <i>
+        Mapping Metadata
+    </i></a>.  Version 1.0 of the orm schema can be
+found at <a class="ulink" href="http://java.sun.com/xml/ns/persistence/orm_1_0.xsd" target="_top">http://java.sun.com/xml/ns/persistence/orm_1_0.xsd</a>.

+                    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, named-query,
+                    named-native-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 also
+                    undefined to have more than one named-query,
+                    named-native-query, or
+                    result-set-mapping of the same name 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
