I'm mostly referring back to Pavel's statements: | 1. Oracle doesn't support this | 2. DB2 has different implementations for z/OS (variadic) and for unix (nonvariadic) With an added #3 which is AFAIK sql server doesn't implement this either (I believe they implement something similar with sp_xml_preparedocument) So even if we are following the spec (which I think technically we may not be), if no other database implements it the way we are, then it really isn't one less function people will have to modify. Which again, I'm not trying to argue against having it, I'm just trying to figure out if there is some specific group that would benefit from it. Robert Treat https://xzilla.net
