First draft of UBL 2.1 PRD2 package

Hello UBL TC,  I have uploaded an initial draft of the UBL 2.1 PRD2 package here:
http://www.oasis-open.org/apps/org/workgroup/ubl/document.php?document_id=42253
The only thing still missing from the current PRD2 package list is the ASN.1 specification, so this version can be considered complete as far as content is concerned.  Please review it carefully and (if you are a contributor) please check to make sure that everything related to your contribution is correctly described.  Jon
