[news.eclipse.modeling.mdt.uml2.ocl] How to change the error message?

[Andreas Werner <andreas.werner@xxxxxxxxxxxxxx>]

Hi,

is there another way to change the content of an error message (if an 
OCL constraint is violated) than modifying the Jet templates?
The default messages are not really convenient for end users, are they?

Perhaps something like an Annotation in the EMF model?

Thanks, Andreas
