This notation form is no longer relevant for SysMLv1.6/1.7
Webel Best Practice: In general, the SysML DirectedFeature approach is more powerful and the notation is cleaner than UML provided/required Interfaces. Prefer SysML DirectedFeatures unless you have a really good reason to use Interfaces!

[CAPABILITY, FEATURE, STYLE, TIP] TIP: MagicDraw/Cameo: Consider showing the Port name and type label inside the Port symbol! CAVEAT: This loses the direction indicators on Ports typed by Blocks with flow properties (but is fine if ItemFlows show the direction, or for "contract ports").
