The xmlns="http://docbook.org/ns/docbook"; declaration makes the stylesheets
interpret the XML file as DocBook 5, not 4.5. 

You have stumbled upon the following gotcha: when producing HTML Help from a
DocBook 5 document, the profiling stylesheets (profile-htmlhelp.xsl instead
of htmlhelp.xsl) must be used.
