No, but the class needs to be in your CLASSPATH.

This will match a MyDateUtility class that is from the package
com.myself.

If you class doesn't belong to any package (by default), you should just
use xmlns:my="http://www.jclark.com/xt/java/MyDateUtility".

Otherwise, this ***looks*** fine.

Hope this helps.
