Error parsing persistence.xml

There are 2 problems if I try to deploy EE5 confirming ear to 7.0.0 Beta2, standalone configuration.

1. If I put persistence.xml if ejb.jar, it throws following exception:

15:04:36,000 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC00001: Failed to start service jboss.deployment.unit."efp.ear"."ejb.jar".PARSE: org.jboss.msc.service.StartException in service jbo
