Thank you very much for the links provided.

I was able to make it work. Here is the code for throwing individual exceptions from within XSLT to the cocoon sitemap:

...
<map:selectors>
  <map:selector name="exception" src="org.apache.cocoon.selection.XPathExceptionSelector">
    <exception name="FileNotFound" class="org.apache.cocoon.ResourceNotFoundException"/>
    <exception name="Transform" class="javax.xml.transform.TransformerException" unroll="true">
      <xpath name="ContentNotAvailableInCountry" test="message='ContentNotAvailableInCountry'"/>
    </exception>
    <exception class="java.lang.Throwable" unroll="true"/>
  </map:selector>
</map:selectors>
...
<map:handle-errors>
  <map:select type="exception">
    <map:when test="ContentNotAvailableInCountry">
      <!-- defined <xsl:message terminate="yes">ContentNotAvailableInCountry</xsl:message> error -->
    </map:when>
    <map:when test="Transform">
      <!-- generic <xsl:message terminate="yes"/> error -->
    </map:when>
    <map:when test="FileNotFound">
      <!-- file not found error -->
    </map:when>
    <map:otherwise>
      <!-- something else -->
    </map:otherwise>
  </map:select>
</map:handle-errors>
...

This works for me. The key is to have the unroll="true" in it + the order of the <exceptions/>.

I will do further testing.

Cheers,
Daniel
