In the context of ARINC653 (but in other cases as well), we need to specific that a Periodic Pattern or Aperiodic or Sporadic is synchronise with the partition (schedulable Resource). that mean this king of events pattern starting synchronously with the partition (that mean the reference is the partition)

So, could add this feature to MARTE to model Partition synchronised events whatever it is periodic, sporadic or aperiodic

Having icons and symbols for stereotypes improves models comprehesibility. For instance, HRM and SRM chapters provide graphical representations for most of the stereotypes. However, the GRM subprofile, which is shared by other chapters (analysis modeling parts of MARTE), has not such graphical representation. We propose to add icons and symbols (likely similar to SRM and HRM's ones) to GRM stereotypes.
