The other solution is to return values in the map that specify error, etc.
If only the Selectors let you expand values....  It would be great to do something
with the CodedSelector like this:

<map:act type="add-work">
    <map:when test="&qout;data&quot.equals({error-type})">
      <map:redirect-to uri="insufficient-data.html"/>
    <map:when test="&quot;jdbc&quot;.equals({error-type})">
      <map:redirect-to uri="database-error.html"/>
      <map:redirect-to uri="success.html"/>

Unfortunately, the sitemap doesn't expand test values.
