**NOTE:** According to the link [1] EJB2.0 is supported with EAP6 so ideally JBoss should be able to parse the "ejb-jar.xml" of version 2.0 DTDs.

**NOTE:** there is a feature request seen for JBossAS7 for requesting support for ejb-jar.xml 2.0 DTDs  [2]

[2] https://issues.jboss.org/browse/JBMETA-354



Version-Release number of selected component (if applicable):
How reproducible:

Steps to Reproduce:
1. Deploy an MDB based EJB jar in EAP6 and use the ejb-jar.xml as mentioned in the issue description.


Actual results:
- EAP6 should be able to parse the ejb-jar.xml properly and should deploy the MDB properly.


Expected results:
- Deployment should be successful.
