UBL Naming and Design Rules (NDR) govern the modeling of documents for the automated generation of validation artefacts (XSD and CVA files).

The base rules are generic and can be used for any CCTS 2.01-based document model and can be found here:

OASIS Business Document Naming and Design Rules Version 1.0

The UBL Committee has documented UBL's use of the generic rules here:

OASIS UBL Naming and Design Rules Version 3.0

See also the spreadsheet editing instructions employing the tools to create the artefacts from the models.
