True, I was inaccurate in my phrasing (but it's moot since JS was the 
first and default <script> language ;-).

Any response?  I shouldn't expect unknown MIME type parameters to cause 
the script content to be ignored, so no worries.  Martin pointed this 
out in another post, thanks to him too.

It's Content-Script-Type 
(http://www.w3.org/TR/html401/interact/scripts.html#h-18.2.2.1), 
atomized as headerContentScriptType at 
http://lxr.mozilla.org/mozilla/source/content/html/content/src/nsHTMLAtomList.h#162, 
but now seemingly not used?  cc'ing jst and peterv.  Since it seems we 
don't use this atom, the answer to your question is "no, but we will 
when we fix the broken content-script-type support!" ;-)
