to be clear;

XSLT 1.0 spec states that MIME types text/xml and application/xml 
'should' be used, though there are a few caveats;

- The spec goes on to say that new media types can 'also' be used, so 
things like text/xsl is fine.

- I tend to avoid the mime-type text/xml....as this conflicts with what 
various specs say on how to determine charset (XML and RFC3023)....

- IE (last time I checked) uses text/xsl

- Mozilla is fine with text/xml and application/xml...and something I 
didnt know (from Jarno's post) apparantly uses text/xsl as well

- and |application/xslt+xml is the mime-type as specified in the XSLT 
2.0 draft spec

|clear as mud....from a server perspective I still tend to first check 
device, then browser, browser type, version....then send the correct 
mime-type (with lang/charset being checked somewhere along that 
sequence) based on the exact browser type/version and XSLT processor 
version.
