/**
 * This interface is to be implemented by a JPA vendor to provide extensions to 
 * the core JPA model.  The core JPA model will provide functionality for JPA
 * spec annotations in java, persistence.xml and mapping (orm.xml) files.
 * The org.eclipse.jpt.core.generic extension supplies 
 * resource models for those file types in GenericJpaPlatformProvider. 
 * 
 * This JpaPlatformProvider implementation most likely only returns providers
 * that are extensions of other platforms.  Then in the GenericJpaPlatform implementation
 * you pass in 1 or more JpaPlatformProviders.
 * 
 * See the org.eclipse.jpt.core.jpaPlatforms extension point
 * 
 * Provisional API: This interface is part of an interim API that is still
 * under development and expected to change significantly before reaching
 * stability. It is available at this early stage to solicit feedback from
 * pioneering adopters on the understanding that any code that uses this API
 * will almost certainly be broken (repeatedly) as the API evolves.
