An Attribute defines a StructuralFeature which contains values for Classifiers or their instances.

Attributes
Primitive Type boolean	isDerived	A derived attribute is one whose values are not part of the state of the object instance, but whose values can be determined or computed. In a sense, all attributes are derived, since it is up to the class's implementation to hold or calculate the values. However, by convention, isDerived indicates that the derived state is based on other information in the model. Modification of the derived Attribute causes the information upon which the Attribute is derived to be updated.
