 ### Fixed ###
+- an empty string as name is treated as no name (as does the server). This, fixes
+  queries for identifiables since it would contain "WITH name=''" otherwise
+  which is an impossible condition. If your cfoods contained this case, it is
+  possible that Records are now matched that were not before. You need to adjust
+  your identifiable definition if this is not wanted.
