DOCBOOK-APPS: No bold body text in PDF

[Steinar Bang <sb@dod.no>]

Platform: DocBook XML 4.1.2, DocBook XSL 1.48 & 1.60.1,
	  Fop 0.20.3rc and 0.20.4

Neither
  <emphasis role="bold">This is bold text<emphasis>
nor
  <thead>
   <row>
    <entry>A table header is bold</entry>
   </row>
  </thead>
is formatted as bold in PDF (though both end up as bold in HTML).

Is this behaviour expected?  Is the problem in the style sheets, or is
the problem with Fop?  Is there a way to change the style sheets to
get this behaviour?

Thanx!
