I would like to know if there is any configuration option which disabled automatic validation messages. It means, those messages included in plugin.properties of org.eclipse.emf.ecore. I would like to show my own custom messages when validating a model, and it shows only those messages defined in that .properties file.
I have defined some .evl constraints defined with its respective error messages, but when I validate a model also appears those errors due to cardinalities. What I need is to know f there is any option to ignore those messages and only show the messages that I have defined in the .evl. For example, I don't want to show messages like this: "The feature xxx of xxx have 0 values and must have at least 1.
To do this you'd need to un-register/suppress the built-in EMF validation rules programmatically (through EValidator.Registry.INSTANCE) but it's not clear why you would want to do this given that these are legitimate error messages. Would it be an option to relax your metamodel instead (i.e. so that it doesn't impose the > 0 constraint)?
