/**
 * An object is an instance that originates from a class.
 *
 *
 *
 * In the metamodel, Object is a subclass of Instance originating from a Class.
 * The Class may be modified dynamically, which means that the set of features of
 * the Object may change during its life-time.
 *
 *
 *
 * An object is an instance that originates from a class; it is structured and
 * behaves according to its class. All objects originating from the same class are
 * structured in the same way, although each of them has its own set of attribute
 * slots. Each attribute slot references an instance, usually a data value or
 * possibly, another object. The number of attribute slots with the same name
 * fulfills the multiplicity of the corresponding attribute in the class. The set
 * may be modified according to the specification in the corresponding attribute,
 * e.g. each referenced instance must originate from (a specialization of) the
 * type of the attribute, and attribute slots may be added or removed according to
 * the changeable property of the attribute.
