 * A data value is an instance with no identity. In the metamodel, DataValue is a

 * applicable to it are pure functions or queries that do not cause any side
 * effects. DataValues are typically used
 *
 * as attribute values.
 *
 *
 *
 * Since it is not possible to differentiate between two data values that appear
 * to be the same, it becomes more of a philosophical issue whether there are
 * several data values representing the same value or just one for each value. In
 * addition, a data value cannot change its data type and it does not have
 * contained instances.
