  Description copied from interface: DataPathNavigator
  
  Q: I really don't know how this thing can be used on queries or scripts... A (roman): Can only be used in stuff like relation-names/field-names. Maybe i can be used on queries, but then it only returns the target type or something.
  
  The idea is that the system can navigate on a schema (like relation, fields, java-bean-properties etc) without having the actual data yet.
