The reason that <noscript> worked is because (IIRC) it was introduced at the same time as <script>. All browsers that supported <script> also supported <noscript>. <nostyle> would cause all legacy user agents to render the content even if they supported styles just fine. > And yes while that is true and for many situations will work fine, there are > other cases you won't and you can get a sloppy or even bad results because > of rendering engine paths.

That doesn't seem like a very serious issue. Just don't use images if you care that much. A large percentage of non-CSS browsers are probably text-based anyway. > For example, using the content property can be somewhat troubling if > style is removed.

Do you have any other examples where this is a significant issue? Those two don't seem like a big deal to me, honestly, even if it were logistically possible to get <nostyle> supported widely enough to be useful. If CSS is necessary for a site to operate, it's probably being misused. If an author is misusing CSS this badly, it's not clear to me why they could be expected to reliably use <nostyle>. The contents of <nostyle> also don't make a difference to almost anyone, so authors who use it won't really understand the purpose it serves and it will probably be misused more often than used.
