Hi,
If optional element exists then Child element
references optional element Else child element
references other required element
<xsl:choose>
<xsl:when test="optional">
<xsl:apply-templates select="child"/>
<xsl:with-param name="ref" select="optional" />
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="child"/>
<xsl:with-param name="ref" select="other" />
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
