Description

The LPG 2 parser gives slightly different diagnosis of errors causing the bcaktracking tests to fail.

The use of ERROR_TOKEN in EssentialOCLErrors.g was slightly pragmatic.

While the change is a nuisance, it may provide an opportunity to do better; this may be an area where the parser has improved.

The backtracking parser supports multiple diagnosis in editors, which are now supported by Xtext. The backtracking parser is heading for deprecation and so further development is unlikely.
