I didn't say the context of the containing element; I said the dependence of the attribute upon the element. That is precisely my point. Adjectives are parts of speech but may not of themselves form what are understood as the parts of sentences or predications. They nevertheless have real meaning, which can be demonstrated in their weight on the semantics elaborated from any particular processing of the substantives upon which they depend. I am wondering if XML attributes are not accurately, and usefully, to be understood in much the same way. I think that your example below serves my point better than yours (even if we dispense with any special pleading for the xml:lang attribute, which is not exactly a routine example of attribute namespacing). This particular attribute in this particular namespace is intended as, effectively, a constant: to impart the semantics of 'being in the vocabulary of the French language' wherever it is used. But in the instance which you construct--and perhaps in any other instance--it is at least as likely that the conflation of content Bonjour! with element <anyOldElementAtAllIDontCareWhich>tests the assertion imparted by xml:lang="fr" as it is that the use of the attribute definitively colors the French-ness of that conflation of element and content. And if that is so, we are back to my original question: when the instance is processed, what semantics are elaborated specifically because of the namespace of the attribute which color the outcome beyond what results from the dependence of the particular attribute upon the particular element in the particular context? > Consider > > <anyOldElementAtAllIDontCareWhich xml:lang="fr">Bonjour! ... > > There's a technical term for Simon's argument in this case: "wrong". > Unless of course you're talking about some general philosophical notion of > namespaces, outside of the formalism in the spec, in which case I freely grant > your point, and Simon's. I'm not, and I wouldn't want such a concession. Simon can speak for himself. I'm not really asking about namespaces. I'm wondering about the weight of an attribute's namespace upon the semantics elaborated from processing that attribute and the element upon which it depends in a given context.
