I am currently using XText 2.17. My issue is that I have to validate the excess whitespace at the end of a parser rule. My current XText code is as below:

grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals hidden()

generate myDsl ""

greetings+=Greeting* ;

Greeting hidden(WS):
'Hello' name=ID WS*'!';

The issue is I don't want to use hidden and should parse white space with a warning. The current code doesn't allow me to do it. It just allows me to write with as many whitespace as possible. Thanks in advance.
