SYSML2_ — Accept action in representative notation tables is confusing and needs cleanup

Clause 7.16.1 (rep. notation for actions) shows a graphical notation example of an accept action corresponding to the following textual notation:

action trigger1 : Trigger 
accept scene : Scene via viewPort;

It shows 3 alternative graphical notations which are confusing and inconsistent.
That graphical representative example needs to be corrected. Here are few issues:

• it shows an unbound parameter "receiver" in 2nd and 3rd examples
• first example uses the type Trigger instead of Trigger1
• 3rd example uses guillemets in the wrong way
• too many options instead of one "canonical" way to do this
• it uses a parameter that in 2nd example called scene and in 3rd example called payload
