The transaction set identifier (ST01) is used by the translation routines of
the interchange partners to select the appropriate transaction set definition
(e.g., 810 selects the Invoice Transaction Set).

Identifying control number that must be unique within the transaction set
functional group assigned by the originator for a transaction set
Reference assigned to identify Implementation Convention
The implementation convention reference (ST03) is used by the translation
routines of the interchange partners to select the appropriate implementation
convention to match the transaction set definition. When used, this
implementation convention reference takes precedence over the implementation
reference specified in the GS08.
