            This is the XML Schema for the persistence object/relational
            mapping file.
            The file may be named "META-INF/orm.xml" in the persistence
            archive or it may be named some other name which would be
            used to locate the file as resource on the classpath.
            Object/relational mapping files must indicate the object/relational
            mapping file schema by using the persistence namespace:
            http://java.sun.com/xml/ns/persistence
            and indicate the version of the schema by
            using the version element as shown below:

                    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
                    be partial.
