Before I make a comment in Bugzilla, I would like to ask several questions. I really like the 5.1 conformance criteria section. However, doesn't the fact that section 5.3 states that the interchange set "MUST" contain an SML URI scheme in each non-null SML reference and the conformance criteria of SML-IF documents states that a conformant document MUST adhere to stipulations in normative sections (I assume 5.3 is classified as a "normative section") mean that a conformant SML-IF document MUST contain an SML URI reference for every non-null SML reference? If so, haven't we just subtly re-introduced Level 2 conformance as the criterion of conformance? Rather than directly stating it, we imply it (which makes it a little more difficult to ferret out of the text). Is this what is intended?? If so, don't we reintroduce the debate we had originally at the F2F for introducing the two "levels"--namely (as I recall), vendors who wish to develop their own schemes don't want to be declared non-conformant? Maybe instead "levels" of conformance, perhaps defining document conformance as in 5.1 and allowing an explicit concept of "interoperability" will resolve the problem. Section 5.3 becomes a section on "Interoperability Criterion" (rather than "SML References"--we seem to have a lot of "SML Reference sections). The SML URI scheme is required for each SML reference to achieve full interoperability. SML-IF documents can be conformant to the spec (in terms of schema structure and requirements) but not fully interoperable (e.g., if they contain an instance of the EPR scheme). Also, a question on the definition of conforming SML-IF Producer: must have a conforming SML-IF Producer be able to literally take *any arbitrary* SML model and generate a conforming SML-IF document--even if the SML model contains non-interoperable reference schemes??? That seems to be calling on the SML-IF Producer to do the impossible.

This does not help with regard to interoperability which is SML-IF's primary goal. Rather, this dilutes the interoperability that SML-IF brings to the table. I propose the following 2 changes: ================= 5.1 Conformance Criteria A conforming SML-IF Document MUST adhere to this specification as described in the normative sections. A conforming SML-IF Producer MUST be able to generate a conforming SML-IF Document from an SML model. A conforming SML-IF Consumer MUST process a conforming SML-IF Document using, in whole or part, semantics defined by this specification. It is OPTIONAL that a conforming SML-IF Consumer process all elements defined in this specification, but any element that is processed MUST be processed in a manner that is consistent with the semantics defined here. ================ Add new section - insert after section 5.2 5.3 SML References An SML reference can contain multiple representations using different reference schemes. SML-IF requires that all non-null SML references in the interchange set MUST contain an SML URI scheme [SML 1.1] representation. Any SML reference MAY also include other scheme representations as well.
