/**
 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Combined Fragment</b></em>'.

 * <!-- begin-model-doc -->
 * A combined fragment defines an expression of interaction fragments. A combined fragment is defined by an interaction operator and corresponding interaction operands. Through the use of CombinedFragments the user will be able to describe a number of traces in a compact and concise manner. CombinedFragment is a specialization of InteractionFragment.
