By adding Invitation ,Withdrawal, Revocation, Late Acceptance and Notice messages as well a definition of dispatch and reach, more of key legal principles such a UNIDROIT, UNCITRAL, UN CISG, Priciples of European Contract Law and UN Rec 31 are covered. /anders -- ///////////////////////////////////// / Business Collaboration Toolsmiths / / website: <www.toolsmiths.se> / / email: <anderst@toolsmiths.se> / / phone: +46 8 545 885 87 / / mobile: +46 70 546 66 03 / /////////////////////////////////////
