Create jdbc job repository using deployment descriptors

The Example for "new Job Repository" (https://docs.wildfly.org/20/Admin_Guide.html#deployment-descriptors) doesn't work properly.

 <jboss xmlns="urn:jboss:1.0">
 <batch xmlns="urn:jboss:batch-jberet:1.0">
 <job-repository>
 <jdbc jndi-name="java:jboss/datasources/ExampleDS"/>
 </job-repository>
 </batch>
 </jboss>

Schema batch-jberet_1_0.xsd alllows only in-memory or named job-repositoryType. 
You get the validation exception by using the jdbc example.

It would be useful to improve the batch-jberet integration so that the example given above would work.
