Hi all,

I am writing a grammar in which I am using the following rule for the qualified name:

QualifiedName:
	ID ("." ID)*;

However, I have a specific case where the element that I will reference is as follows:

Wheel:
name="wheel" ;

And is located inside an element that is identified by an id.

Car:
name=ID
wheel=[wheel|QualifiedName]

So if I try to write the following grammar:

Audi
ID.ID.ID.wheel (let's say that I am referencing this from another file where I will have multiple ID in front of wheel).

I get mismatched expecting RULE_ID. I also tried it with STRING but it doesn't work. wheel in this case will be used as a keyword so any suggestions on how to change the qualified name to accept this specific case?

Thank you!
