Docbook and Apache Forrest generation

I am trying to use Docbook as a source for documentation that lives as
part of a web site generated by Apache Forrest. According to the Apache
guys the path to do this is Docbook XSLT -> HTML -> Forrest XSLT ->
HTML.
This works OK, but there are several elements that seem to get doubled
up by the Forrest stuff. It appears that the <span class=""></span>
elements in the generated HTML trip up the Forrest processor.
Is there a way to easily modify the Docbook XSLT to not produce these?
Or, since it is mostly a problem with the title and TOC, not have those
generated?
Thanks,
Eric J.
