Find an element that is already converted/rendered the way you want, and
then grep for the definition of that element in the stylesheet.

For example, when I was working this out, I decided to look at how 
<filename> was handled.

    % cd /usr/local/share/sgml/docbook/dsssl/modular/html
    % grep 'element filename' *
    dbinline.dsl:(element filename ($mono-seq$))

If you go digging around in dbinline.dsl you'll see how all the inline
element conversion to HTML is done.  For example, other sequences available
are

    $charseq$
    $monoseq$
    $bold-seq$
    $italic-seq$
    $italic-mono-seq$

Grepping for "(define ($bold-seq$" will show you where this sequence is
actually defined, so you can the underlying DSSSL.

Everything I know about DSSSL so far I've picked up from

   a) a rudimentary knowledge of Emacs lisp

and

   b) studying Norm's stylesheets.

Hope it's useful.  Any questions, drop me a line.
