+/**
+ * Do not copy connector related elements, i.e.
+ * 1. UML connectors with stereotype FCM.Connector
+ * The rationale behind this is that we want to avoid copying a FCM connector from the source model
+ * into the target model since the target model should only contain the reified form of the connector
+ *
+ * 2. UML classes that are stereotyped as interaction components
+ * We do not want to copy interaction components, since they typically need to be instantiated.
+ * TODO: there is no check whether we are actually in a template. An interaction component might be fixed (i.e. not
+ * depend on template instantiation) and needs to be copied in this case.
+ * (in most cases, these are not copied anyway, since these are in a different model,
+ * but we do not want to exclude the case of defining model-local connectors)
