SYSML17 — If there is no «port» keyword in UML-2.5.1 or SysML-1.6 it should be removed from Figure 9-8

If there is no «port» keyword in UML-2.5.1 or SysML-1.6 it should be removed from Figure 9-8: Water Delivery association block

Although it is explained in the text, I have had many clients and training customer unnecessarily imitate it.

It [EDIT: the «port» keyword] is introduced in Figure 9-8, and then never used in any of diagrams that follow.

If it must stay, it should be made clear that it is a user-defined stereotype keyword.

BTW: I address this in my own models by using conventions for Port type naming: I_Contract, F_FlowStuff etc.
