If the 'test' XPath expression is does not result in a boolean value, then it is converted to a boolean value according the the XPath 1.0 specification. In particular, if the XPath expression results in a set of objects, then 'test' is considered to be true if and only if the set is not empty.<P><P>Note that more than one 'visit' tag may be executed for the same object identified by the parent 'visitor' tag.<P> </P>
