+A better alternative to the TERM member is the the RPN
+member, which is a reference to a Net::Z3950::RPN::Term object
+representing the scan cloause. The structure of that object is the
+same as for Term objects included as part of the RPN tree passed to
+search handlers. This is more useful than the simple TERM because it
+includes attributes (e.g. access points associated with the term),
+which are discarded by the TERM element.
