Date: Wed, 18 Jun 2008 15:54:46 +0100 To: "'XuAnthony'" <xuhaitiancn@msn.com>, <xmlschema-dev@w3.org> Message-ID: <AF6B183EA5D74248B16A88C167CF485D@Sealion> Because the prefix "lib" refers to the namespace http://dyomedea.com/ns/library, your references to lib:name and lib:person are references to the element declarations named "name" and "person" in the schema document for target namespace http://dyomedea.com/ns/library. So you have indeed defined them. I notice that in your instance document <library xlmns=http://dyomedea.com/ns/library "xmlns" is misspelled. This could cause a great deal of confusion! In fact, I see your schema even declares an attribute with this name <xs: attribute name="xlmns" use="required"> presumably because the schema was generated from the instance?
