DOCBOOK-APPS: how to get xsltproc to generate "tidy" html?

i'm sure numerous folks will tell me that this is a silly
thing to do, but is there a parameter somewhere that will
tell xsltproc to generate tidy html from docbook, so that
it's at least remotely humanly readable, rather than one
long line?  just curious.  having it a bit more readable
makes it easier to debug glitches when one is forced to
look at the page source.  thanks.
