(12142) B.4.5.4 Block Definition Diagram: Should say 'white diamond (shared AggregationKind)' not 'white diamond (composition)'

Mon, 12/31/2007 - 09:24 — drkelly

SysML1.0:

'B.4.5.4 Block Definition Diagram - Power Subsystem
..
Note how the of white diamond (composition) on FrontWheel and BrakePedal denotes the same “use-not-composition” kind of relationship previously shown in Figure B.16.'

The choice of the word 'composition' in combination with the white diamond is unfortunate, as it implies 'composite' AggregationKind.

Rewrite to say 'white diamond (shared AggregationKind)' rather than 'white diamond (composition)':

'Note how the of white diamond (shared AggregationKind) on FrontWheel and BrakePedal denotes the same “use-not-composition” kind of relationship previously shown in Figure B.16.'
