LOTOS is an ISO standard [11] whose given semantics is in terms of structured labelled transition systems. In this semantics (referred to here as the standard semantics), each data variable in a process is instantiated by every possible value of its corresponding type, resulting in infinite transition systems (both in breadth and in depth).
