I've turned off schema validation for ejb-jar.xml (for backwards compatibility) otherwise some of the tests don't pass that do system property replacement or xml enums, e.g. the message driven tests where transaction-type should be "container" or "bean" according the schema | <message-driven> | <ejb-name>TestMDB</ejb-name> | <ejb-class>org.jboss.test.messagedriven.beans.TestMessageDriven</ejb-class> | <messaging-type>javax.jms.MessageListener</messaging-type> | <transaction-type>${test.messagedriven.transactionType}</transaction-type> | We probably want to revisit this test so we can enable schema validation by default?
