does a server have to announce that style sheets are "text/css"?

I don't know if it's part of the "standard", but mozilla and IE (IIRC) 
require the correct mime type for stylesheets when running in strict 
mode. I ran into this myself recently when I was updating some internal 
apps to be 4.01 compliant.

If you're using mozilla, open the javascript console and load 2 pages: 
the first with a linked stylesheet not of type "text/css" and the second 
with the correct mime type. You'll notice the warnings when in quirks 
mode. It's just the way it is. And IMHO it's a good thing since we're 
supposed to be running in compliance with the standards.

It's easy to fix as well: just make sure the default handler is run for 
your .css files. Assuming apache:

<Location /css>
   SetHandler default-handler
</Location>
