SysMLv1: TIP: You can strengthen the ill-defined semantics of Property 'aggregation' (an AggregationKind) by applying custom Stereotypes to a Property, documented with its intended use. Not perfect, but better than not. EXAMPLE: «assembled»

A property typed by a Block that does not have composite aggregation is classified as a reference property. Source OMG Systems Modeling Language (SysML) 1.7beta1
A FlowProperty need not have 'composite' AggregationKind, it can be 'shared' or 'none'. (The MagicDraw/Cameo default is 'none').
The aggregation of a property stereotyped by ParticipantProperty shall be none Source OMG Systems Modeling Language (SysML) 1.6
