How to configure xts subsystem using CLI command in JBoss EAP 6 ?

Issue

I am working with an application team that is making use of xts.We make it work by adding following tag manually to a standalone-full-ha.xml file:

<extension module="org.jboss.as.xts"/>

<subsystem xmlns="urn:jboss:domain:xts:1.0">
     <xts-environment url="http://${jboss.bind.address:127.0.0.1}:8080/Service"/>
</subsystem>

However I cannot find CLI documentation anywhere for enabling xts. Can you get me pointed in the right direction?
