True; but we can't alter the document structure like that, because we
need to be able to persist.  (The HTML rendering engine in IE4 is also
an authoring system - e.g. it's used by Outlook Express, the email
client in IE4.)

? I was under the impression they supported the :link and :visited
pseudoclasses.  Mind you, I think they do skip :active...

I had a similar experience with Netscape.  You're right, the spec is not
ambiguous - it says you don't have to implement this.  Section 2.1,
paragraph three: "A UA is not required to reformat a currently displayed
document due to anchor pseudo-class transitions.  E.g., a style sheet
can legally specify that the 'font-size' of an 'active' link should be
larger that [sic] a 'visited' link, but the UA is not required to
dynamically reformat the document when the reader selects the 'visited'

That said,  IE4 does in fact support this - did in Platform Preview 1,
if I recall properly.  A VERY cool effect. Obviously, dynamic (and
partial) reformats are no problem for us - they're the core of our
Dynamic HTML technology, allowing us to dynamically (and interactively)
change the content and presentation.

Whoa, </MODE TYPE=MARKETING>.  Sorry about that.

I agree whole-heartedly with you on this one.
