Hmm.....there's one browser feature this would allow that I like.
If the user configures the browser's "Accept" values to completely
reject, say, postscript, the browser, finding itself with a postscript
content-type specified in the anchor, could ignore the anchor and not
render it as a link. If the user sets "Accept" to prefer one
content-type over another, the "preferred" type could be rendered
differently than the less-preferred (different colors, different
underline, whatever). Sort of like the "inspect link" feature request
from earlier this week -- don't have to traverse it to get info about
it. The "Accept" headers work on a config-by-config basis; content-type
in the anchor could work on a link-by-link basis for a similar purpose.
