Audience value not exporting to output file in XSLT transform - xslt

Question

I'm having trouble getting the value in the audience tag to appear in my output file while running an XSLT transform on a DITA map.
This is the snippet of my input with audience="Alaska":
<topicgroup>
<topichead navtitle="Alaska Property and Casualty Adjuster Law" locktitle="yes" audience="Alaska">
<topicgroup>
<mapref href="Qbank/maps/Adj_Unit_AK.ditamap" format="ditamap"/>
</topicgroup>
</topichead>
</topicgroup>
Here's the portion of my XSLT script that contains the <!--Add audience--> section:
<xsl:template match="topichead">
<xsl:param name="all_topic_refs" select="topicref[#type='topic' or #type='concept']" as="element()*"/>
<xsl:param name="all_question_refs" select="topicref[#type='question']" as="element()*"/>
<xsl:param name="all_exam_refs" select="topicref[#type='exam']" as="element()*"/>
<xsl:param name="audience" select="topichead[#audience='property' or #type='concept']" as="element()*"/>
<xsl:param name="all_exam_maps" select="descendant-or-self::examMap" as="element()*"/>
<xsl:copy>
<xsl:attribute name="navtitle">
<xsl:choose>
<xsl:when test="navtitle">
<xsl:apply-templates select="navtitle"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="#navtitle"/>
</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
<!--Add audience-->
<xsl:attribute name="audience">
<xsl:value-of select="#audience"/>
</xsl:attribute>
<xsl:apply-templates select="*[not(self::examMap[#assessment_type='test-exam-primary']) and not(self::navtitle)]">
<xsl:with-param name="all_topic_refs" select="$all_topic_refs"/>
<xsl:with-param name="all_question_refs" select="$all_question_refs"/>
<xsl:with-param name="all_exam_refs" select="$all_exam_refs"/>
<xsl:with-param name="all_exam_maps" select="$all_exam_maps"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
The output is giving me this with empty quotes in the Audience tag:
<topichead navtitle="Alaska Property and Casualty Adjuster Law" audience="">
<topicref href="questions/inslic_assess_Adj_AK.dita"/>
</topichead>
It pulls over the navtitle correctly but I can't figure why it won't pull over the audience input. Any help would be most appreciated.

I will assume your XSLT stylesheet is applied at a certain stage from a plugin when publishing the DITA XML content using the DITA Open Toolkit. You can add an xsl:message inside the xsl:template which matches the topichead:
<xsl:message><xsl:copy-of select="."/></xsl:message>
Then look in the console output when publishing to see exactly on what XML element the template is applied.
The DITA Open Toolkit publishing engine has a pre-processing step which applies filtering and removes all profiling attributes from all elements.
https://www.dita-ot.org/dev/reference/preprocess-debugfilter.html
To preserve the profiling attributes when publishing you need to specify a DITAVAL filter file which specifies that the profiling attributes should pass through to the published output. Something like:
<val>
<prop action="passthrough" att="audience"/>
</val>
