What was said by Rick Jeliffe regarding the current schema draft is true (and anyone who is interested is recommended to red the actual XML Schema WD at http://www.w3.org/TR/xmlschema-1/ and http://www.w3.org/TR/xmlschema-2/.) However, I would like to correct a possible misimpression that might arise from the turgid wording in the current public draft and also from Rick's statement "Then (s4.3.2) there is an attribute xsi:schemaLocation that can be put on any instance element. It allows the location of the schema to be declared. ..." After extensive debate, the XML Schemas WG decided that the xsi:schemaLocation attribute serves as a hint, not a mandatory directive. That is, the processor of an instance is welcome to look at the URI referenced by the value of xsi:schemaLocation, but is not required to. It may process an instance document using a different schema set (or no schemas at all). The relevant phrase is "unless directed otherwise" in the following passage from the 1999-12-17 structures draft: "Again, unless directed otherwise general-purpose schema-aware processors must attempt to dereference each schema URI in the value of "schemaLocation" to obtain a schema..." This is in recognition of the fact that, ultimately, the processor of a document determines what processing is done. xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
