The following two examples are identical:
<genkey alias="apache-group" storepass="secret" dname="CN=Ant Group, OU=Jakarta Division, O=Apache.org, C=US"/>
  
<genkey alias="apache-group" storepass="secret" >
  <dname>
    <param name="CN" value="Ant Group"/>
    <param name="OU" value="Jakarta Division"/>
    <param name="O"  value="Apache.Org"/>
    <param name="C"  value="US"/>
  </dname>
</genkey>
