Unlike DTDs, documents written to a particular schema are not _required_ to point to that schema from the document, so although Google currently reports approximately 4M xml documents of which 590 contain reference to XMLSchema-instance (i.e. .01477 %), which is a prerequisite for "referencing [an] XML Schema specification", this figure doesn't actually tell you very much at all about the extent to which W3C XML Schema is used. > So, is it still right, and how I can know the current extent of XML > Schema on the Web? So yes, in some sense it's right that very few XML documents explicitly reference W3C XML Schemas. But without sampling XML documents out there, checking their namespaces, if any, etc., it's very hard to get an objective measurement. ht -- Henry S.
