This Transformer runs through the expressions of the query For each OUTER(pp) expression it performs an implicitJoin for the join manager of the surrounding query and replaces the OUTER(pp) expression with the base node alias '.' the field. We need a join manager hierarchy to do this. We have decided to limit the outer statement to the join manager of the directly surrounding query so that the user can specify the absolute path in a normalized form.
