Constants for UML model properties names are defined in several classes.
Use com.nomagic.uml2.impl.PropertyNames for standart UML metamodel property names.
Use com.nomagic.uml2.impl.PrivatePropertyNames for auto-generated opposite property names.
The events’ names related with model creation/ deletion are listed in the com.nomagic.uml2.ext.jmi.UML2MetamodelConstants class.
