Very true. Maybe the explicitness of HTML appealed to me; escape
sequences feel more like... you know, computer "codes" and all. (which
of course is what all this is anyway! So what's wrong with that?)

You're probably right, and CSS is practically a different animal, and I
guess at best one would have to settle for a stripped-down version of
HTML (in which case, why bother?) And again, all this is before we even
consider other issues; I can't shake the feeling that there security
nightmares lurking inside this idea.
