Subject: ATG2 CCTS Schemas with UBL
Just to mention I've tried the ATG2 CCTS schema with UBL 1.0 (see attached) and found
hardly any problems
all I had to change in UBL (so it seems so far)
were some complexContent to simpleContent
(since some ATG2 UDTs are simple where they are complexTypes in UBL 1.0)
I've not tried this on instances yet.
All the best
