This sounds interesting (and very important). I am uncertain what it means. Would you mind explaining this further, in terms that people (such as myself) without a background in SGML can understand? For example, what does it mean that an XSD only defines the grammar rules for a subset of all possible conforming documents? That doesn't jive with my experience with or understanding of XSDs.
