RE: AS2 XML requirements (was Re: HL7 Standards Process)

Is the transaction identifier qualified by another field or is there a need
to set up a registry of transaction set identifiers? I suspect that HL7
would prefer to maintain its own identifiers without worrying about
collision with another standard or having to sit through length debates
about whether to use a hyphen or an underbar.
