Thompson a écrit : > In the context of an extended discussion at the recent TAG f2f > regarding references to potential time-varying specification URIs [1] I encourage you to read the section 2.2.3 Normative (and Non- Normative) References http://www.w3.org/TR/qaframe-spec/#reference The Good Practice 8 specifically. On Wed, 10 Aug 2005 12:30:15 GMT In QA Framework: Specification Guidelines At http://www.w3.org/TR/qaframe-spec/#ref-define-practice Good Practice 8: When imposing requirements by normative references, address conformance dependencies. What does it mean? Each addition of a normative reference to the specification has deep implications on the technology. Specification editors are responsible for reviewing the consequences in terms of consistency, precision, possible future changes or obsolescence as well as use of the technology under specific conditions. Why care? A specification defines a technology with a potentially long lifespan. The choice of precise and exact normative references is thus fundamental. Using a normative reference that evolves over time might endanger the specification or other specifications relying on it. A vague reference to the other specification as a whole may leave room for conflicting interpretations or choices among variations permitted by the other specification. For the Working Group, reducing the degree of ambiguity or variation in the normative references minimizes or removes the possibility of misunderstanding. For implementers, it removes ambiguities and contradictions between different sets of technologies. It creates a stable environment for their development efforts. For conformance testing to be practical, all requirements need to be unambiguous, including those imposed by normative reference to other specifications. -- Karl Dubost Montréal, QC, Canada http://www.la-grange.net/karl/
