The value of Essential MOF (EMOF) lies in its ability to provide a straightforward framework for mapping MOF models to implementations such as XML Metadata Interchange (XMI) for simple metamodels2. This allows for easier integration and manipulation of MOF models in various platforms and tools.

In UML, ValueSpecifications are used to specify the value of an element. The UML 2 Specification does not define a metaclass named StringExpression. Instead, it provides a metaclass named OpaqueExpression, which can be used when an expression is written in a language that is not directly interpretable by the model. Since there is no metaclass called StringExpression in the UML 2 Specification, there is no explicitly intended use for it within the UML metamodel. The absence of this metaclass suggests that any use of a concept called "StringExpression" would not conform to standard UML 2 practices and would likely be part of an extension or profile, not the core UML metamodel.

Given that the system is inStateA1, the sequence of triggers that will move the system toStateCmust take into account the transitions and their associated triggers as defined in the UML state diagram. Starting fromStateA1, the triggera5will cause a transition withinStateA, followed bya6, which moves toStateA2. The triggera5is not relevant as it is an internal transition inStateA1. Then,a3(the exit action forStateA) anda2would be followed to leaveStateAaltogether. Once out ofStateA,a1is used to transition toStateB, wherea10is an entry action, not a trigger. Finally, to get fromStateBtoStateC, the triggersa11followed bya12are needed. This sequence of triggers reflects the correct usage of exit, entry, and transition triggers as defined by UML state machine semantics.
