Defining particular behavior when a type is seen is not the same as  
standardizing it, in my opinion. Particularly if we had an  
informative note that the type is not recommended for authors.

"text/xsl" is used very commonly in xml-stylesheet processing  
instructions, since IE recognizes only that type and not the properly  
registered "application/xslt+xml". Example:

<?xml-stylesheet type="text/xsl" href="bottles.xsl"?>

However, I am not sure how much either of these MIME types is used  
over the wire - most XSLT style sheets that I can find are sent with  
the header "Content-Type: text/xml", or "Content-Type: application/ 
xml" this being apparently the default for the .xsl extension in  
popular http servers.

It does seem to me, given the widespread use in the xml-stylesheet  
PI, that if someone does send this MIME type they probably intend it  
to be processed as XML. But how common it is to do that, is an open
