I am unsure of the status of UBLer (Oriol) and UBLish (Chee-Kai), and 
soon the community will have the publicly-available work from Turkey (Asuman).

Close but not quite ... there will be an NDR 2.1 to cover the 
differences.  For example, qualified data types are going to be 
expressed outside of the spreadsheets, thus outside of the XSD 
schemas, realized entirely in a second-pass value validation 
process.  Accordingly, *all* BBIEs will be based on unqualified data 
types in the schema.  I've proposed the use of OASIS context/value 
association (CVA) files to express all information item 
qualifications to satisfy the qualified data type concept.  Users of 
UBL will be able to integrate their own information item 
qualifications with the committee qualifications so that requirements 
such as field length limits (not a constraint imposed by the 
committee but possibly necessarily imposed by a community of users) 
can be incorporated into their own processes:

The Schema Generation Task Group (SGTG) will (I hope!) this week be 
publishing to the UBL TC for committee review the proposed strategy 
document for UBL 2.1 validation artefacts.  I have it all drawn up, 
documented and I have created a working prototype environment where 
I've created the necessary UBL 2.1 artefacts using UBL 2.0 spreadsheets.

I look forward to hearing any comments/suggestions should we make it 
to the committee review status this week.
