section in the wiki doc.

TypesafeMetamodel -> StaticMetamodel
See Appendix A.4 of the latest 20090723 version of the specification (you 
may not have access to this latest version) on p.468

"Renamed TypesafeMetamodel annotation to StaticMetamodel."
Here is a link into the StaticMetamodel annotation interface in the 
javax.persistence package (replaces TypesafeMetamodel)
http://fisheye2.atlassian.com/browse/eclipselink/trunk/jpa/plugins/javax.persistence/src/javax/persistence/metamodel/StaticMetamodel.java

package javax.persistence.metamodel;
public @interface StaticMetamodel {
   Class<?> value();
}

See the following bug and design issue #36 for any implementation changes 
required for this interface (currently none).
