The subquery operator behaves like any other operator. It can have a name (here complex) and must provide the source of the subquery. This can be a file, contain the querytext (QUERYFILE) or this can be a running query (queryID or queryName), or the query text can be given inside a string (query). In the last case, the parser must be set (if other than Odysseus Script). Hte outputconnectors in the ouside query are not necessary.
