Hi, I've got several errors validating a correct xsd file in oXygen Eclipse Plug-In. Importing a XSD File Error: src-import.3.2: An <import> element information item that had no namespace attribute was found, so the imported document cannot have a targetNamespace attribute. However, the targetNamespace 'uri:namespace' was found in the imported document. @see: http://www.w3.org/TR/xmlschema-1/#src-import Occurs when: <xs:import schemaLocation="anotherfile.xsd" /> Only works when: <xs:import namespace="uri:namespace" schemaLocation="anotherfile.xsd" /> This is incorrect!! Use Attribute in a Element Error: s4s-att-not-allowed: Attribute 'use' cannot appear in element 'attribute'. Occurs when: <xs:attribute name="type" type="xs:string" use="required" /> Only Works when: <xs:attribute name="type" type="xs:string" use="required" /> This is incorrect because use attribute is OK. What I have to configure for oXygen work corrrectly?! Thanx
