IValidIdentifier very strickt for ClassConcept Names

Hi folks,

i m just wondering if it is possible to get around the IValidIdentifier restriction of MPS.

Hello-World should be a valid identifier for a class concept, however, there is a property restriction. Is there a way to get around that restriction? Of couse, i could build my own ClassConcept and overwrite the property restriction for the name prop. But then, i have to do the same for the constructor - derive my own concept. Is there another road to take?   

Cheers, Daniel
