[ https://issues.jboss.org/browse/WFLY-2212?page=com.atlassian.jira.plugin.... ] Lincoln Baxter III commented on WFLY-2212: ------------------------------------------ Actually, I don't know if this was the case in JPA2.0, but notice that omitting any data-source results in a schema valid persistence.xml. If one of jta-data-source or non-jta-data-source were required, then I think the schema should show that, right? -- This message is automatically generated by JIRA.
