uml.metamodel.uml.Element.source();
ElemDirectRelationshipToPS.src(ProblemStatement);
TypeName(Var)
TypeName.relName(RelVar,SrcVar,TrgVar)
E.g. in the spec and tutorial that I have I cannot find the description of the syntax
"uml.metamodel.uml.Element.appliedStereotype(AppliedST, DomainSpecificProblemStatement, StType);"
as you told me in one of your last answers.
