Need clarity regarding the precedence on configuration resolution while using wildfly-config.xml

In EAP 7.1 Development Guide

18.1. Client Configuration Using the wildfly-config.xml File

Currently, there is no clarity over precedence when it comes to loading the file and how is the configurations for different clients are resolved.

There should be more details on the behavior of how client configuration resolution works and its precedence.

Like,
1) When is wildfly-config.xml considered and when it's ignored?
2) Is there changes in the way configuration is loaded for a standalone client vs client deployed on EAP?
