Docbook <bibliosource> gets lost in the transformation

Question

I have the following structure

    <informalfigure xmlns="http://docbook.org/ns/docbook">
      <info>
        <bibliosource>Photo: John Doe</bibliosource>
      </info>
      <mediaobject>
        <imageobject>
          <imagedata contentdepth="30mm" contentwidth="35mm" fileref="path/to/img.jpg"/>
        </imageobject>
      </mediaobject>
      <caption>
        <para>Here goes the caption for the image</para>
      </caption>
    </informalfigure>

<imagedata> and the <caption> get rendered but the <bibliosource> is gone after the transformation.

I'm using the docbook-xsl-1.77.0/xhtml/docbook.xsl for the transformation... I need some guidance on where/how to change the xslt so that <bibliosource> gets transformed properly.

Thanks!

Here is a simple solution. Add the following to your XHTML customization layer:

<xsl:template match="d:caption">
  <div>
    <xsl:apply-templates select="." mode="common.html.attributes"/>
    <xsl:call-template name="id.attribute"/>
    <xsl:if test="@align = 'right' or @align = 'left' or @align='center'">
      <xsl:attribute name="align"><xsl:value-of select="@align"/></xsl:attribute>
    </xsl:if>
    <xsl:apply-templates/>
   </div>
   <div><xsl:value-of select="../d:info/d:bibliosource"/></div>   <!-- This line added -->
</xsl:template>

The above works with the namespace-aware XSLT stylesheets (docbook-xsl-ns).

If you use the non-namespace-aware stylesheets (docbook-xsl), the corresponding customization becomes:

<xsl:template match="caption">
  <div>
    <xsl:apply-templates select="." mode="common.html.attributes"/>
    <xsl:call-template name="id.attribute"/>
    <xsl:if test="@align = 'right' or @align = 'left' or @align='center'">
      <xsl:attribute name="align"><xsl:value-of select="@align"/></xsl:attribute>
    </xsl:if>
    <xsl:apply-templates/>
   </div>
   <div><xsl:value-of select="../blockinfo/bibliosource"/></div>   <!-- This line added; note blockinfo -->
</xsl:template>

The text of the <bibliosource> element will appear in a separate <div> directly below the caption. The original template is in graphics.xsl.
