XML NDRs: UBL 2.0, 2.1, CEFACT 2.1, 3.0

["Pim van der Eijk" <lists@sonnenglanz.net>]

Hello,

 

For a new project that I'm starting on I am doing some research on XML Naming and Design Rules. I am trying to understand how some of the recent specifications relate to each other and differ from past versions.   I am hoping some people on this list can help here (and I'm assuming more subscribers to this list will be interested in this). 

 

The September 2010 draft UBL 2.1 has an Appendix G on the naming and design rules used for UBL 2.1:

Previously, in December 2009 the UBL TC approved NDR 2.0 as a Committee Specification.

1) What are the changes (if any) between this CS and the UBL 2.1 Appendix G NDR ?  

 

In August 2007 a comparison was posted between the CEFACT version 2.0 NDR and the (then-current) UBL NDR:

In the mean time CEFACT has published a version 3.0 of its XML NDR specification:

2) What are the changes (if any) between the CEFACT version 3.0 NDR and the latest UBL NDRs ?   

 

3)  What are the changes (if any) between this version 3.0 CEFACT NDR and the earlier CEFACT version 2.0 NDR ?
