Processing a target node with the auto-label mode causes information about its cross-reference labels to be output. This mode is used only during the creation of site maps.

It differs from the for-xref-label mode, to be described below, in that all the wrapper elements inside the xs namespace are output, whereas for-xref-label only gives the content of the cross-reference label.

The default implementation below simply calls on the for-xref-label mode to get at the actual content of label. In the wrapper element xs:label, the absolute URI of the target node is recorded.

xsl:template match="*[@id]" mode="auto-label"
      xsl:param name="base-uri"

      <hs:label>
        xsl:attribute name="href"
          xsl:call-template name="absolute-uri"
            xsl:with-param name="base" select="$base-uri"
            xsl:with-param name="href" select="concat('#', @id)"
          
        

        xsl:apply-templates select="." mode="for-site-map-label"
      </hs:label>
    

Processing a target node with the for-xref-label mode returns the XHTML1 markup for its cross-reference label.

For example, processing a section would typically result in the content of its h child element, possibly preceded by its chapter or section number.

xsl:template match="x2:section" mode="for-xref-label"
      xsl:apply-templates select="x2:h" mode="title-text"
    

xsl:template match="*|text()" mode="for-xref-label"
      xsl:textunknown label
