NDR Checklist Clarification

[Chin Chee-Kai <cheekai@softml.net>]

R13:
----------
For every primary representation term used in the UBL model, a named
complex type MUST be defined.
----------
R14:
----------
For every secondary representation term used in the UBL model, a named
complex type MUST be defined.
----------

How do "primary representation term" and "secondary representation
term" relate to each other, and to "representation term" and 
"qualifier representation term"?  Are they 4 different concepts,
or some are synonyms or something else?

In the spreadsheet models, there are only "qualifier representation
term" and "representation term".  Please clarify.




R90:
-----------
A RootSchema in one UBL namespace that is dependant upon type definitions
or element declarations defined in another namespace MUST NOT import
schema modules from that namespace.
-----------

What is this talking about??
