UML14 — Page 98: arrowhead issue

Summary: Page 98 Filled arrowheads, stick arrowheads are dangerously close. For
instance, Powerpoint only offers the filled and in other situations this
would double for the stick arrowhead. In other words, too much semantic stress on
arrowhead shape when many common tools like Powerpoint can"t differentiate.
[Powerpoint is a simple example. I have watched tool vendors and publishers take
a diagram like this and replace with their own versions of a black/white;
open/closed arrowhead and accidentally transform the meaning. Even from
UML generalization to stick arrowhead for dependency is not that hard -
I"ve seen it done!]

Considered and declined.
