SYSML11 — Section: More constraints for flow ports

The flow port and the flow specification need more constraints and clarification statements. What does it mean to type a flow port with a block that realizes many flow specifications? What does it mean to type a port with block that realizes many interfaces including some flow specifications? Is it allowed that a flow specification is part of a realization relationship? How to define a complex flow port that uses more than one flow specification?

Any property (including flow ports) that are typed by a classifier that realizes
multiple interfaces (including flow specifications) means the value will support the
features of all the interfaces. This is UML semantics that is not necessary to
restate in SysML. Flow specifications are based on interfaces, and participate in
realization relationships like any other interface. A classifier can realize multiple
interfaces, including flow specifications. This is UML syntax that is not necessary
to restate in SysML.
