marker points and curves confusion

In the dictionary it states “Curve and irregular polygon graphics can be drawn with a marker at each vertex"
I have set the markerdrawn property to true, and markerPoints to a listOfVertexes (copied from user manual).
The curve is formed of the oval with a startangle of 180 and an arcangle of 90 ( so it is the bottom left quarter of a circle).
I had hoped for markers at the ends of the lines, but I have nothing. I know they are technically not vertices, but I can’t think what else would be on a curve.. What should I see?
Oh wait. Unless a curve is not a section of a oval, but a freehand curve transformation of a polygon….
But if I change a polygon into a freehand curve, the marker points disappear. Wah.
OK sorry for the stream of consciousness stuff. The questions:
A/ Can I place shapes at the ends of an arc of a circle?
B/ Can I match a polygon ‘curve' to any defined arc, effectively achieving the same by a workaround?
