/**
 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Instance</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * The instance construct defines an entity to which a set of operations can be applied and which has a state that stores the effects of the operations. In the metamodel Instance is connected to a Classifier that declares its structure and behavior. It has a set of attribute values matching the definition of its Classifier. The set of attribute values implements the current state of the Instance. Because Instance is an abstract class, all Instances are either Object or DataValue instances.
 * 
 * The data content of an Instance comprises one value for each attribute in its full descriptor (and nothing more). The value must be consistent with the type of the attribute. An instance must obey any constraints on the full descriptor of the Classifier
 * of which it is an instance (including both explicit constraints and built-in constraints such as multiplicity).
