You are reading docs for community JBoss AS 7.0 Final
But you are using Red Hat JBoss EAP 7.0.0.GA which is much much newer version of server.
Starting with version 8, community JBoss AS was renamed to WildFly.
EAP7 is based of WildFly 10, so if you are looking at community docs you should look at WildFly 9 & 10 ones.
EAP7 and WidFly 8+ are all EE7 certified unlike AS7 that was still EE6
