Description Henrik Lindberg CLA 2011-01-29 13:40:14 EST 
When there is a duplicate token in a terminal, there is no error in the .xtext editor, but when generating the grammar, an error is produced with a reference to the InternalMyLexer.g - "duplicate token type '-' when collapsing subrule into set".

terminal NAME :
	'::'? (('0'..'9')|('a'..'z')|('A'..'Z')|'_' | '-' | '-' | '.')+ 
	('::' (('0'..'9')|('a'..'z')|('A'..'Z')|'_' | '-' | '-' | '.')+)*
	;
