The WG as a group rejected (when? I think it was design issue 210 in the development-issues list) a proposal to specify more clearly the order in which augmentation and validation occur. If I may be allowed to quote the description of the resolution from the issues list: RESOLVED 2000-02-04 (Berkeley ftf): to pass over this topic in silence (i.e. not to specify that augmentation occurs before validation, nor that validation occurs before augmentation, nor that the order is not specified, nor that the order is immaterial because any order which obeys all the constraints expressed in the spec will produce the same results). Dissenting: LBNL, W3C. Abstaining: NCR. http://www.w3.org/XML/Group/xmlschema-current/issues.html#AugmentationAndValidation When I began this note, I was intending to say that since we had decided not to say anything explicit, David's intuition had jolly well better be correct since otherwise where would we be -- but now I notice that last bit where the WG also refused to say explicitly that the order is immaterial, and I infer that we would, if David's intuition were faulty, be exactly where we are: with a problem on our hands. Next week in London, members of the dissenting minority will be accepting apologies from members of the majority who have seen the error of their ways. Evidence of contrition (e.g. a round or two) will be expected. -CMSMcQ
