Subject: Re: [ubl] RE: [ubl-ssc] Codelist dependencies

I agree with Sylvia, we need to get on top of this issue.  My 
understanding is that the UBL Schemas will not need a qDT because we are 
no longer restricting the schemas for specific code lists.  in other 
words we dont need a qDT for CurrencyCode because as far as the schema 
goes it is just a CodeType.  The validation of values now happens 
outside the schemas.

However, what we still need is the metadata that was in the qDT to be in 
the UBL schemas (and models).  For exmaple, which code lists (eg the 
genericode schema) should be used for validation.  I dont think the 
current NDR defines this metadata so where do we put it?

Does anyone have ideas for this?
