I'm not sure what you mean by distinguishing "style format" and "data
format", but I'm pretty certain that XSL as it stands today is
"transformation rules format" + "data format". <fo*> objects seem like a
data format to me.

XSL specifies both the transformation rules _and_ the data format of the
results, but forces them to exist under the same name. A "text/xsl" format
makes perfect sense if you mean "convert to a document containing <fo:*>
elements"; as you point out, it makes much less sense to say "convert to an
XSL stylesheet". To make this distinction, however, one would have to
acknowledge that XSL = XTL (transformation) + XFL (formatting)... Nice
example of why this is a technical issue, instead of a political one.
