Minor thing:

For all the quickstarts that have child maven modules under the root module for the QS, the parent of the root is org.wildfly.quickstarts:wildfly-quickstart-parent, and then the QS root is the parent of the child modules. But with ejb-txn-remote-call the parent of the child modules is org.wildfly.quickstarts:wildfly-quickstart-parent.

This is no big deal at all, and if there's a reason it's this way, just close this. Otherwise this is a minor suggestion to make things consistent.
