DOCBOOK-APPS: HTML Help (htmlhelp.xsl) topic ids

Any way to code docbook source so that htmlhelp.xls includes topic ids in
the generated HTML Help?
We want to to enable context-sensitive calls from an application to specific
help topics. I can't find a clue either in the DTD or the style sheet as to
how this might be implemented.
