XSLT over SAX?

Has anyone put any thought or effort into basing an XSLT processor on SAX?

This would have the benefit of providing a standard syntax for
performing some simple transformations of large files.

I'm guessing that a proactive analysis of a stylesheet for things
that require non-sequential access to the DOM would be difficult
(in some cases requiring knowledge of the XML instance).

So instead, it could just start processing the XML instance as a
stream, and if/when the stylesheet requires an operation entailing
moving backward in "time", it would raise a runtime exception.
