As Shmuel said, parser rules are effectively fragment rules. I don't
see how a (non-)fragment concept would help in the case with non- 
keywords. You will always have to supply some context and custom code to
make the right decision.

Could you elaborate what you mean by a fragment parser rule and how this
would solve the problem?
