RE: seeking a validator
SST asked: >> A reader asked me if I knew of any software that would let you take an >> arbitrary SAX stream or DOM tree and validate it against a DTD (heck, >> multiple DTDs) of the application's choosing, without relying on the >> DOCTYPE declaration. I don't have a solution for this problem. You might be able to intercept or insert a DOCTYPE event between the SAX and validation layer in one of the more layered parsers like IBM's. But I think I do understand the need the provoked it. I discussed this a bit in a comment to the W3C Schema work group (http://lists.w3.org/Archives/Public/www-xml-schema-comments/1999JulSep/0052 .html) which started as a rant on the recently introduced minAbsoluteValue and maxAbsoluteValue attributes and then tried to explain the distinction between schema constraints (hopefully implied by the physical nature of a system) and application (as in EXE, maybe more appropriately processor) constraints (based on the limitations of the implementation of an application). For example, a well defined address schema would allow you to express non-US addresses. However, it would be useful for an application to say that beyond the requirements of the schema, it had additional requirements (such as a US address) and that if the document didn't meet these additional requirements then it wasn't interested in processing it. xml-dev: A list for W3C XML Developers.
