XSL:FO forced page break between <glossentry> elements?

Platform: Intel Pentium M, Ubuntu 5.10 "Breezy Badger",
	  docbook-xml 4.4-4
	  docbook-xsl 1.68.1-0.1ubuntu1
	  xsltproc 1.1.15-0ubuntu1
	  fop-0.91beta

I have a docbook article with a <glosslist>, where in PDF, the content
of one of the <glossentry> elements overlaps with the line and page
number at the bottom of the page.

I tried inserting a <?fo-pagebreak ?> PI before the offending
<glossentry> and matching it with the following XSLT template:

  <xsl:template match="processing-instruction('fo-pagebreak')">
    <fo:block break-before="page"/>
  </xsl:template>

However, this didn't have any effect.  And looking at the resulting
.fo file there is no <fo:block break-before="page"/> element.

If I put the PI eg. before a <section> there will be a
<fo:block break-before="page"/> in the output, and there will be a
page break in the resulting PDF.

So the reason is probably that the template isn't matched inside the
<glosslist>.  Does anyone know what I can do to make it match inside
<glosslist>? 

Thanx!
