RE: What are schemata
Tim Bray wrote: ---------------------------- Hmm, this line of thought may be perpetuating what I see as one of the shortcomings of DTDs, namely that the DTD has to describe the whole document, i.e. a class of languages. What about partial validation/constraints? I think it's important that child-of-DTD support compond documents & partial validation. So in the terms above, maybe these things define sets of elements and attributes, rather than whole documents. ----------------------------- I think focusing on elements and attributes is an excellent idea. I'd like to see XSchemas applicable to fragments as well as to documents. I've been pondering this in connection to some object store ideas I had while writing that Building the Filesystem into the File paper a few months ago. 'Documents' in the traditional sense are still popular, but I don't know how much longer we'll really be working with them. I think fragments, subsets, and combinations are going to be much more popular in the reasonably near future. Compound documents and partial validation are a fact of life, or will be once XML, XLink, and XPointer receive more widespread usage. I think we can prepare XSchemas to support these (partial validation is easier) without turning somersaults and cartwheels simultaneously.
