Hi,

Now I want to know How to extend it to add my own validations?

Thanks,
Mark

Mark,

You can declare constraint in the model via annotations and when such
annotations are present, a validator will be generated:

http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclipse.emf.doc/references/overview/EMF.Validation.html

I'd suggest having a look at EcoreValidator. If you want better
messages, you'll want to define a plugin class for your model in the
*.genmodel so you can add to the plugin.properties and use them in your
validator.
