+     Type-7 sort is an extension to the Bib-1 based RPN query where the

+    <para>
+     The objectives for introducing Type-7 sorting is that it allows
+     a client to perform sorting even if it does not implement/support
+     Z39.50 sort. Virtually all Z39.50 client software supports
+     RPN queries. It also may improve performance because the sort
+     critieria is specified along with the search query.

+     specifies the

+     only the generic part is handled. If generic sortKey is of type
+     sortField, then attribute type 1 is present and the value is
+     sortField (InternationalString). If generic sortKey is of type
+     sortAttributes, then the attributes in list is used . generic sortKey
+     of type elementSpec is not supported.
