My personal view is that XML Schema is _not_ about data modelling, it's about flexible and powerful document structure definition. Tree-structured documents are a good transfer medium for application data, but XML Schema as such does not specify how to map from application data to document and back. A declarative specification would be nice -- XSLT can manage one direction, via its element extension mechanism. The Cambridge Communiqué [1] gives a fuller version of this story. ht [1] http://www.w3.org/TR/schema-arch -- Henry S.
