I asked Leonard for clarification, and here is his answer:

> To avoid misunderstanding: Do you mean that a reader should process   *all* actions (in the order you describe), or just the first one?

We should be careful about the terminology here.

The PDF that I saw had multiple *annotations* (a Link and a Widget) that had
overlapping rectangles.  *for normal processing* - When the user clicks in a
certain point, the interactive PDF processor should walk through the array of
annotations on the page dictionary and execute any action(s) associated with
the first one that it finds that covers the clicked point.  If, however, there
is no action to be taken, then move on to see if any more annotations are
covering the hit point. 

Now, beyond that, the processor could do what it wants.  For example, support
left vs. right clicks.  Or support a normal mode and an editing mode. Or ....

Why you folks are thinking about this area - don't forget to support QuadPoints
for annotation (esp. Link) boundaries.  And there is also a proposal in the
works at ISO for non-rectangular links (where an arbitrary path can be
provided).
