On the other hand, as the HTML5 drafts do not in any way suggest that 
markup be minimized, a warning (or even an informative message) might be 
somewhat odd - especially since many people have the habit of using 
them, and there are usually many more important things to consider.

Reading again my own previous message I see a typo, or rather lack of 
typo here:

The first tag is correct of course - I meant to include a typo like 
text/ccs instead of text/css (I've seen this happen).

And I think issues like this would be much more important than any 
message about a redundant attribute. (The only real problem with 
redundant attributes is that you may mistype then - and might use quite 
some time in trying to find out why your style sheet or your JavaScript 
code seems to be ignored.)

So I think a validator could issue an informative message, possibly even 
a warning, if it encounters <style type=...> or <script type=...> with 
an attribute value outside a specific small list, saying something like 
"limited or no support in web browsers".
