A property is a structural feature of a classifier that characterizes instances of the classifier. A property related by ownedAttribute to a classifier (other than an association) represents an attribute and might also represent an association end. It relates an instance of the class to a value or set of values of the type of the attribute. A property related by memberEnd or its specializations to an association represents an end of the association. The type of the property is the type of the end of the association.
