The OASIS Universal Business Language TC  members have recently approved a Committee Specification Draft (CSD) and submitted it for 45-day public review:
Universal Business Language Version 2.2
Committee Specification Draft 01 / Public Review Draft 01
21 December 2016
This specification defines the Universal Business Language (UBL) version 2.2, an open library of standard electronic XML business documents for procurement and transportation such as purchase orders, invoices, transport logistics and waybills.
UBL 2.2 is that it is completely backward-compatible with UBL 2.0. UBL 2.2 is technically a minor release however it does add 16 new document types for eTendering, for transportation, and for business directories and agreements. This brings the total number of UBL business documents to 81.
