I wanted to know how you knew if/when you have reached the limits of XSLT,
and it's time to look at a DOM / SAX solution? What sorts of
transformations are too difficult/awkward to accomplish in XSLT and are
better left to DOM / SAX implementations?

DOM/SAX seems a pretty low-level alternative
to XSLT.

You might want to have a look at Omnimark
instead for more complex transformations.
