That's a different question, I think.  DBTNG uses arrays and named placeholders.  It sounds like David is talking about XPath based queries, which are another animal entirely and not DB portable.  David, can you elaborate here?

DBTNG does not allow the reuse of placeholders within the same query, because PDO doesn't either.
