SYSML12 — Notation for multiple item flows

Notation for multiple item flows. The UML specification provides a compact notation for multiple information items flowing in the same direction. A similar notation should be provided in SysML, but this is not explicitly called out. Recommendattion. Add a sentence at the end of section 9.3.1.4 which describes diagram extensions for item flows consistent with the UML approach that reads "When several item flows having the same direction are represented, only one triangle is shown, and the list of item flows, separated by a comma is presented." Also, include the multiple item flow notation in the Item Flow entry in Table 9.1.

Accept proposed resolution with text that describes diagram extensions for
multiple item flows consistent with the UML approach, and with some additional
constraints on ItemFlow. Note that an item flow can have only one conveyed
classifier. A future revision should consider a constraint that “An ItemFlow must
have a single item property” since the item flow and item property should be
viewed as a single concept in SysML
