DOCBOOK-APPS: two-sided <set> and pagenumbers

Using dsssl stylesheets, I have a problem with some pagenumbers being
placed in the wrong side on <set> title pages, when setup for two-sided
printed output.

When a <set> title page appears on en even page, the pagenumber is
printed in the right side instead of left.

Actually, I think the right thing would be if all <set> and <chapter>
title pages were forced to appear on uneven pages - can this be done?
