I geuss there are several usages.. My comment was because I had forgotten about the term schemata, which was used previously in some reports I wrote with murata-san. Let me go back to my usual cribs.. First of all brandizing it as XML Schema by W3C itself is quite inconvenient. Anyways, these are my current thoughts... there are several solutions to schemas, each with different expressive power and properties. W3C's is one such -- but it requires the *largest* amount of work before it can be used -- first ensuring that orthogonal things are kept orthogonal, or even if combined, explained in an understandable manner -- for example, recently the discussion on what elements with global scope declaration mean -- do they mean root elements, do they specify the root element of a substitution group?? right now each person is using it for his/her own purpose, and that happens to be only one of such conflicts. Suppose someone wants to use both the features -- then can he do it??? I think in such cases, claims such as XML-Schemas support both should be carefully thought out and clearly explained -- it is *very* difficult for us to understand what to do in such a situation. you are the experts in this, you have to teach us clearly. Also, you can take this for granted -- 1-unambiguity is *absolutely* unnecessary -- it does lot of harm, and no good?? -- but it was there from the orignal SGML DTD... There is another solution which is regular tree grammars, which is an absolutely necessary step for query. Query analysis can never proceed without this -- so this has to stay. <warning>speaking for himself only</warning> cheers - murali.
