This could be an excellent project for cooperation between SC.1 , UN/CEFACT and TBG3-Transport and TBG2 ( for UNeDocs ) . In addition to the CMR consignment note , the ITC Bureau might also find it useful to have a presentation made at its June meeting on UN/CEFACT recommendations and work related to documents , including the United Nations Layout Key and United Nations electronic Trade Documents ( UNeDocs ) .
