I think your suggestion is probably on target, iff the purpose of
the embedding is to act as some sort of scripting language for the
web page. If it's to act as a container for metadata, or some sort
of statements about the content of the web page content, then <style>
is probably not appropriate. There's also the danger that browsers
may try to interpret its content as Javascript. There'd have to be
some testing to make sure that certain SCL syntax constructs aren't
interpreted as Javascript.

If it is, your example is almost exactly right. The only thing
missing would be to apply for a MIME type for SCL, and then
using the 'type' attribute, as in:
