Flattened html/docbook.xsl to work in Firefox?

Does anyone have a flattened, single-file docbook.xsl (i.e. without
external entity references and includes) that will work when read
by Firefox using an xml-stylsheet processing instruction? Firefox's
XSLT parser can't cope with external external entities, and some of the
relative pathnames in the XSLT files seem to confuse it as well.

I made a start at consolidating all the includes but haven't reached an
error-free version yet, so if someone has invented this particular wheel
already I'd be grateful to know.
