Warning about 'hippotranslation:translated' being declared in descriptor but not in CND

After the changes made in GOGREEN-1055 there is a warning in the logs:

[INFO] [talledLocalContainer] 19.11.2012 13:33:03 WARN [org.hippoecm.editor.type.JcrTypeDescriptor.validate():530] Super type hippotranslation:translated is declared in descriptor, but is not defined as super type in CND for hippogogreen:event

We need to look into that!
