Hi Eric,
Indeed, this is a bug in the template with match="question" in fo/qandaset.xsl.
I've fixed it in SVN for the next release, and you can use this version in
your customization layer:
<xsl:template match="question">
<xsl:variable name="id"><xsl:call-template name="object.id"/></xsl:variable>
<xsl:variable name="entry.id">
<xsl:call-template name="object.id">
<xsl:with-param name="object" select="parent::*"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="deflabel">
<xsl:apply-templates select="." mode="qanda.defaultlabel"/>
</xsl:variable>
<xsl:variable name="label.content">
<xsl:apply-templates select="." mode="label.markup"/>
<xsl:if test="contains($deflabel, 'number') and not(label)">
<xsl:apply-templates select="." mode="intralabel.punctuation"/>
</xsl:if>
</xsl:variable>
<fo:list-item id="{$entry.id}" xsl:use-attribute-sets="list.item.spacing">
<fo:list-item-label id="{$id}" end-indent="label-end()">
<xsl:choose>
<xsl:when test="string-length($label.content) > 0">
<fo:block font-weight="bold">
<xsl:copy-of select="$label.content"/>
</fo:block>
</xsl:when>
<xsl:otherwise>
<fo:block/>
</xsl:otherwise>
</xsl:choose>
</fo:list-item-label>
<fo:list-item-body start-indent="body-start()">
<xsl:choose>
<xsl:when test="$deflabel = 'none' and not(label)">
<fo:block font-weight="bold">
<xsl:apply-templates select="*[local-name(.)!='label']"/>
</fo:block>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="*[local-name(.)!='label']"/>
</xsl:otherwise>
</xsl:choose>
<!-- Uncomment this line to get revhistory output in the question -->
<!-- <xsl:apply-templates select="preceding-sibling::revhistory"/> -->
</fo:list-item-body>
</fo:list-item>
</xsl:template>

Subject: [docbook-apps] <qandaset defaultlabel="none"> FOP error
Hello, I'm unable to build a PDF from a docbook 4 document that has a <qandaset
defaultlabel="none"> tag in it. If I remove the attribute, everything works
fine. If I leave it in, I get the following errors:
The process 'Apache FOP' ended with code: 1.
The error was:
ERROR - Couldn't find hyphenation pattern for lang="en".

Is this a known bug? I'm not sure whether the problem is with docbook-xsl or
fop. Is ther a workaround for this that doesn't involve changing my XML source
code?
