XML Configuration
The EclipseLink ORM schema (eclipselink_orm_1_0.xsd) can be used with the following header:
<?xml version="1.0" encoding="windows-1252" ?> <entity-mappings xsi:schemaLocation="http://www.eclipse.org/eclipselink/xsds/orm xsd/eclipselink_orm_1_0.xsd" version="1.0" xmlns="http://www.eclipse.org/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
