EDI ID Qualifier for User Defined External Id Types

Hi

What is the EDI ID Qualifier for User Defined 1, User Defined 2, User Defined 1 (External ID Types in TN prfoiles)?

For DUNS the Qualifier is 01 and for Mutually Defined IDs the qualifier is ZZ. Similarly I want to know the EDI ID Qualifiers for User Defined External ID Types.

Regards
Ravi.
