Damn the purists! But it's going to die in SysMLv2 anyway. SysML: Syntax ain't Semantics: FUN CHALLENGE: SysMLv1 block property aggregation: 'The tornado chaser plane "has" a chaser car "with" a chaser team.' 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.

Next snippet Like UML, SysML defines no specific semantics or constraints for properties with shared aggregation, but particular models or tools may interpret them in specific ways.
