In particular, it doesn't seem like this needs to be defined in the MIME sniff spec. There's no harm in the browser sniffing more non-scripted types than the spec says, if it's just for labeling or handling at the OS level. It's when one browser handles something as completely safe and another handles something as live, or when a browser displays a file differently than another browser, that there's a problem, really. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
