See, I would really want something that adds to the DOM like CSS does. The more I hear and read about GRDDL, the more I like it as an item, but the more I also do not think it does why I would like, or accomplishes what the average HTML author needs. It sounds *great* for a "Web Developer", but for someone generating static (or relatively static) HTML *documents*, it isn't sounding like a good fit. J.Ja
