Q and A labeling problems in HTML

["Ursula A. Kallio" <uak@nerp.net>]

I am trying to create an appendix of FAQs and started here:
http://www.sagehill.net/docbookxsl/QandASetsHTML.html#QandAlabels

Specifications:
xsltproc
fop-0.20.5
docbook-xsl-1.69.1
Ubuntu

If I _do not_ include the following parameters in my HTML customization 
layer, an inherited number preceeds each question and answer set:

<xsl:param name="qanda.defaultlabel" select="1" />
<xsl:param name="qanda.inherit.numeration" select="1" />

If I _do_ include these parameters in my HTML customization layer, 
nothing preceeds each question and answer set.

I expect the output to look identical to the output described above.

How can I get the parameters to behave as expected?

PS. If I can explicitly get the parameters to behave as expected, then I 
can globally make changes to the numbering scheme. I do not want to have 
to touch the XML to solve this.
