[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: W3C XML Schema Questionaire
 I agree, Rick, as long as we have some means to determine the scope of "pressing needs". For the Schema designers, following your train of thought, the first consumers are the other spec writers. For the example Amy and Michael discuss, the consumers are product managers and developers. We have to differentiate the requirements of these different consumers. Schema is a very big departure from traditional markup technology. As one local described it, "I feel like I am designing a document according to the rules of Grady Booch". With XML 1.0, we had lots of experience to draw on, so it could be done quickly. With Schema, we have DTDs in the mainstream community, and the input from the formal language designers, database designers, etc. That is a wide scope. Because we have working tools like XDR, and because it is still early, I would not be disappointed to see Schema return to the drawing board for another round. On the other hand, that should be done in my opinion, only if there are real flaws. As SGML showed, complexity and obscurity are not sufficient to reject a specification, but it may be a reason to create a simpler version. In this case, we already have a simpler version.

The idea of the CR period is to allow extensive implementation experience to tell. For example, Arnold Curt's project: I am happy to report (unofficially, but as a member of the WG not paid by commercial interests) that his feedback (like that of other developers) seems to be being treated just as seriously as feedback from commercial developers. > A "flawed" standard (we probably used euphemisms such as "slighly > buggy" or "not completely stable") was considered to be better than no > standard. In retrospect, I think we did the right thing. Yes, that is a very important criterion: does the spec meet the actual pressing need of the day? What is the pressing need: is it to support being able to define SVG, XSL-FO, XHTML, XBase, etc? Is it to support e-commerce? Is it to integrate Java and SQL systems? Is it to allow types for defining user interfaces? One can evaluate XML Schemas on general terms as a universal schema language. But it is more important at this stage, IMHO, to evaluate it in terms of its sufficiency for meeting the pressing needs of the day as the bottom line.
