I thought I posted this before, but it seems I didn't. If you're going to keep this attribute...

We try to avoid attributes on the root element of a subsystem. So something like this would be better:

```
<subsystem xmlns="urn:jboss:domain:batch:1.0">
   <job-repository type="xyz"/>
</subsystem>
```

This is really just about the look of the xml. Having the attribute on the root management resource for the subsystem is fine.
