Hi all, In the W3C Schema 1.0 spec you can find this note about imports: "NOTE: The above is carefully worded so that multiple <import>ing of the same schema document will not constitute a violation of clause 2 of Schema Properties Correct (§3.15.6), but applications are allowed, indeed encouraged, to avoid <import>ing the same schema document more than once to forestall the necessity of establishing identity component by component. Given that the schemaLocation [attribute] is only a hint, it is open to applications to ignore all but the first <import> for a given namespace, regardless of the ·actual value· of schemaLocation, but such a strategy risks missing useful information when new schemaLocations are offered." Does it mean that you can't have 2 schemas defining different elements for the same namespace and then import both from another schema? Should everything for a given schema be defined in just one schema file? If you have a big schema definition for different functional areas, it might be useful to split the schema in several files so you don't need to import elements that you won't be using. It looks like Schema 1.1 is keeping this note. Can anybody tell me the motivation for this note in the schema spec? Thanks.
