> Maybe we could have a service per persistence provider that is based on a configuration settings.
> Questions:
> 1.  Where do the persistent provider jars go in the system?  Should we deploy them somehow?
> 2.  Each persistence.xml specifies the javax.persistence.spi.PersistenceProvider class name (via provider element) that it will use (defaults to whatever the AS7 default persistence provider).  The persistence.xml also allows vendor properties to be specified.  We could have an optional property "org.jboss.jpa.provider.versionSpecifier" that matches a specific version of the provider.
> Is this the best way to allow different versions of persistence provider?
> 3.  How could we best dynamically build a ModuleDependency on a persistence provider jar that 
> could be injected into a deployment (perhaps from JPADependencyProcessor)?
