I think that this was just a "for instance" - it might be just as well
to talk about some other element, like bidi or sup elements in HTML 4.0.

As far as the Flash goes, I just want to clarify Gez's points.  The
issue is not that the Flash movie's accessibility information is not
revealed to MSAA, but that a major AT doesn't look at the MSAA data that
is provided.  Other screen readers and talking browsers do read the MSAA
data, so it is present.

All of this is a bit of an aside to the clarification of baseline, but
if we're talking about Flash as an example we should have the facts
