> In domain mode, it should be possible to start two nodes, each belonging to a different site and get them to join the inter-site cluster providing a single profile.
> To be able to do that, the following needs to happen:
> * A cache's backup site name needs to be able to be defined via a system property, e.g.
> {code}
>           <backups>
>             <backup site="${test.site.local.name:NA}" strategy="SYNC"/>
>           </backups>
> {code}
> * A jgroup stack's relay remote site name needs to be able to be defined via a system property, e.g.
> {code}
>           <relay site="${test.site.local.name:NA}">
>             <remote-site name="${test.site.remote.name:NA}" channel="xsite"/>
>           </relay>
> {code}
> With these changes, it should be possible to define a single profile, and then override site local and remote names via system properties, e.g.
> {code}
>         <server-group name="site-earth" profile="clustered">
>             <jvm name="default">
>                 <heap size="64m" max-size="512m"/>
>                 <jvm-options>
>                     <option value="-Djgroups.join_timeout=1000"/>
>                     <option value="-Djboss.default.multicast.address=234.99.74.14"/>
>                     <option value="-Dtest.site.local.name=EARTH"/>
>                     <option value="-Dtest.site.remote.name=MOON"/>
>                 </jvm-options>
>             </jvm>
>             <socket-binding-group ref="xsite-sockets"/>
>         </server-group>
>         <server-group name="site-moon" profile="clustered">
>             <jvm name="default">
>                 <heap size="64m" max-size="512m"/>
>                 <jvm-options>
>                     <option value="-Djgroups.join_timeout=1000"/>
>                     <option value="-Djboss.default.multicast.address=234.99.74.24"/>
>                     <option value="-Dtest.site.local.name=MOON"/>
>                     <option value="-Dtest.site.remote.name=EARTH"/>
>                 </jvm-options>
>             </jvm>
>             <socket-binding-group ref="xsite-sockets"/>
>         </server-group>
> {code}
> Right now no system property substitution happens for the elements above and hence it's not possible to achieve this with a single profile. Instead, profiles need to be duplicated making it hard to maintain.
