A DESCRIPTION OF THE REQUEST :
http://docs.oracle.com/javase/9/tools/javac.htm#JSWOR627 is supposed to list all valid -Xlint values but it neglects to mention "requires-automatic" and "requires-transitive-automatic" added by https://bugs.openjdk.java.net/browse/JDK-8178011.

These flags are present in JDK 9 GA.

JUSTIFICATION :
Users with non-Java9 dependencies will need to be able to know how to disable the "requires-automatic" warning.
