> Currently Deployment Overlays allow only the replacing whole resource files.  It would be nice to also be able to overlay System Properties that take precedent over globally defined properties.
> ie.
> {code:xml}
>     <deployment-overlays>
>         <deployment-overlay name="myOverlay">
>             <system-properties>
>                 <property name="datasource" value="java:jboss/datasources/controller"/>
>             </system-properties>
>             <deployment name="controller.war"/>
>         </deployment-overlay>
>     </deployment-overlays>
> {code}
> Usecase:
> Have two deployments active of the same application, run-time configured by descriptor replacements via System Properties.
