Subject: Re: Question on CCTs vs Data Types
Fred, Please see comments below: <Quote1> The "attributes" in the PCX file (like Identification Scheme. Identifier) ARE Supplementary Components of the CCT Identifier. Type. </Quote1> Ok, but what would example values be for each of these attributes? <Quote2> Right. The CCT's are listed exhaustively in the normative CCTS itself, so are not subject to user registration. A registry implementation could pre-register them though. </Quote2> I should have been more specific here. I meant to say that these appear to be unregisterable - whether by user, or pre-registered. So what I meant to say is that, according to my intepretation of the CCTS, it is impossible to register a CCT as represented in the CCTS because a CCT (e.g. "Identifier. Type") is much too generic to have attributes such as "Identification Scheme. Identifier", etc. - but with example values (as requested above) my perception of this may change. <Quote3> Hmmm, I'd hope that the CCTS features will be regular features in the ebXML registry, and not "cutom" slots. </Quote3> The OASIS/ebXML Registry TC decided quite a while ago that we would not create new "hardcoded" (or extrinsic, as we say) classes for Core Components. Rather, we would create a Technical Note that would instruct implementors how to customize their implementations for Core Components in a standard way using Slots to represent the metadata attributes in the CCTS. <Quote4> Well, this has been discussed at length within CCTS and the conclusion was that your "Base BCC" is in fact a Data Type. So please don't introduce a new proprietary concept! </Quote4> Thanks, I will definitely keep that in mind in writing the Technical Note. A question, please: referencing CCTS p.12 example, we have a Data Type called "Country" (Country. Identifier). We will need to represent the valid list of Country Codes for this Data Type. Can you please tell me how this would be done, starting with the lowest level of CCT? This is where I'm not clear, and I'm seeing discrepancies in the CCTS.

So the Content and Supplementary Components of a CCT will not be restricted (other than their Primitive Type demands).
