John,
It is true that static viewers are not required to support hyperlinking.
The reason for this is that we were thinking of printers as one class of
static viewers.

However, it does seem like the SVG spec should formally mention a
particular type of viewer being "static plus hyperlinking". This is
pretty much what Batik 1.0 shipped (correct me if wrong) and matches
with the sort of functionality people think about with Acrobat Reader
(although recent versions of Acrobat support JavaScript onto its own
[non-compliant with DOM] APIs).

I'll forward this idea to the SVG working group.
