I'm saying: I want a database that can do XML, by which I mean infinite levels of attributed nested sequenced constructs. You're saying: since this is the basic structure used by object databases, what you really want is an object database. Maybe. The hypothesis that object databases are a good basis for general-purpose high-performance XML repositories is one that's plausible on the face of it, but I have yet to see existence proof that it really truly works. I also know about other groups working hard building native XML repositories on a technology basis that has nothing to do with OODBMS, and their hypotheses look equally plausible to me. And I haven't seen their stuff proved in action either. What was really worrying me was what I thought was an assertion that a repository that directly models XML document structures on a large scale wasn't interesting; I think it is. -T. xml-dev: A list for W3C XML Developers.
