ITransactionalOperationtrue if this ITransactionalOperation is
actually changing model data (instead of only affecting the
visualization). Otherwise returns false. The content
relevancy of an ITransactionalOperation can be checked to
determine if the execution of the operation will affect the model, for
example, to set an editor's dirty flag.isContentRelevant in interface ITransactionalOperationtrue if this ITransactionalOperation is
