Using FOP .93 with DocBook 4

I saw an earlier message on this topic. I am getting the same error
message (shown below) inspite of using DocBook XSL 1.73.0. What should I
do?

javax.xml.transform.TransformerException:
org.apache.fop.apps.FOPException:
file:/D:/ProjectsTest/DocBook/andromda-tutorial-java/targetalt/pdf/andro
mda-tutorial-java.fo:1:12831:
Error(1/12831): No element mapping definition found for
(Namespace URI: "http://xml.apache.org/fop/extensions", Local Name:
"destination")

Thanks.
