+The sort command takes a sequence of sort specifications. A sort
+specification holds a field (sort criteria) and is followed by flags.
+If the sort critieria includes = it is assumed that the sort SortKey
+is of type sortAttributes using Bib-1. The integer before the = is
+the attribute type and the integer following the = is the attribute
+value. If no = is in the SortKey it is treated as a sortfield-type
+of type InternationalString. Flags observed are s (sort case
+sensitive), i (sort case insensitive), < (ascending), > (descending).
