Dear Xtextlers!

Please provide the opportunity to dump out optional keywords, for instance by means of something similar to 'UnassignedTextToken' like a 'UnassignedKeywordToken'.

Rational:

Consider the grammar fragment

State returns synccharts::State:
  (type=StateType)? ('state')? (id=ID)? (label=EString)
  (outgoingTransitions+=Transition ("," outgoingTransitions+=Transition)* )? ';'

and the instance

state A;
state B --> A;

For simplification purposes we want to allow

A;
B --> A;

, as well, but want to serialize the above (canonical) form.

Reproducible: Always
