	No. The use of stylesheets to render a document has been in the
computer industry for quite a while. It's existed in markup (as in SGML)
since the early to mid 80s, I believe.

	This is an old idea. Reading their patent closely, they're
attempting to claim ownership of an idea that predates any use they've had
for it by at least fifteen years.
