HyperMSC - a Graphical Representation of TTCN

The development of an MSC based graphical representation of TTCN is part of the ETSI project STF 156 on 'Specification of a Message Sequence Chart/UML format, including validation for TTCN-3'. The most important language constructs of TTCN can be translated into corresponding MSC constructs in a straightforward manner. However, it turns out that without certain extensions and modifications, the ITU standard language MSC is not capable to produce a sufficiently transparent and readable graphical representation of TTCN. In order to arrive at a really convincing solution, HMSCs are re-interpreted in a way, which has an analogy in hypertext -like specifications. MSC references may be shown also in an expanded manner and non-expanded MSC references may contain hypertext -like descriptions instead of pure reference names. As a result, there does not exist a strict borderline between HMSCs and BMSCs any longer. Such a generalisation of MSC is really efficient only together with a c...
