Actually, I don't think I claimed any virtues to be *unique* to DSSSL.

Yes. This is the question of standardized formats vs. downloadable
programs. Instead of standardizing math (or even HTML) we could just
require everyone to supply Java Applets that render their documents.
Anybody who wanted to do anything other than view the documents would be
screwed, but JavaSoft would be happy!

That's true. I suspect that both will be implemented in IE 4.0 or 5.0
and perhaps Netscape 5.0 or 6.0 and authors will have to learn both and
choose. That's too bad. On the other hand, perhaps "Document Object
Model" scripts will become testing grounds for new ideas that can then
be incorporated in a rigorous manner into DSSSL. I would rather avoid
the bifurcation of effort and education, but I suppose that is what will
separate the professional publishers from the amateurs.
