+OpenJPA has extended the JPA 2.0 schema to include elements and attributes corresponding
+to OpenJPA extended metadata and mapping annotations. The schema are contained in 2
+files: <ulink url="http://openjpa.apache.org/builds/latest/docs/schema/extendable-orm.xsd">
+extendable-orm.xsd</ulink> and
+<ulink url="http://openjpa.apache.org/builds/latest/docs/schema/openjpa-orm.xsd">openjpa-orm.xsd</ulink>.
+The extendable-orm.xsd file provides copies of some of the JPA 2.0 schema elements with additional schema to make it 
+extendable.
+The openjpa-orm.xsd file extends the extendable-orm.xsd with OpenJPA specific elements and attributes representing
+OpenJPA annotations. Currently, only a subset of annotations have actually been implemented, and some of those
+have been partially tested. The current status can be found by comments in the
+<ulink url="http://openjpa.apache.org/builds/latest/docs/schema/openjpa-orm.xsd">openjpa-orm.xsd</ulink>

+In order to use the OpenJPA extensions in your mapping file you must include the namespaces for these 2 new
+schemas as well as for the schema for JPA 2.0, as shown in the following example:
