Aloha. I'm in need of a little enlightenment (or a club over the head) in regards to the proper use of namespaces for the following scenario. I've got two schemas, A & B, that each define an element named EltC. A and B both use the same targetNamespace. A and C are both defined by a "standards body" so I do not want to modify their definitions. If I want to create another schema, Z, which aggregates A & B (i.e. A & B are children in Z), I have the problem of a duplicate definition of EltC. I have, to this point, tried creating Z by <include> or <import> of A & B. Both of which give the problem of a duplicate definition. This seems so be an issue of polymorphism to me. My question is... how can I properly <import> (or <include>) A & B in Z such that there is not this definition conflict? Is this even possible if A & B have the same targetNamespace value? fyi - The actual application is that A and B correspond to Request and Response -type definitions and Z then is an interface that defines the interaction. (Abbreviated) Schema definitions follow... Mahalo for any suggestions. --Chris //### A.xsd #### <xsd:schema targetNamespace="StandardURI" xmlns="StandardURI" xmlns:xsd=http://www.w3.org/2001/XMLSchema elementFormDefault="qualified"> <xsd:element name="EltC"> <xsd:complexType> <xsd:sequence> <xsd:element ref="EltD"/> <xsd:element ref="EltF"/> </xsd:sequence> <xsd:complexType> </xsd:element> </xsd:schema> //### B.xsd #### <xsd:schema targetNamespace="StandardURI" xmlns="StandardURI" xmlns:xsd=http://www.w3.org/2001/XMLSchema elementFormDefault="qualified"> <xsd:element name="EltC"> <xsd:complexType> <xsd:sequence> <xsd:element ref="EltD"/> <xsd:element ref="EltF"/> <xsd:element ref="EltG"/> </xsd:sequence> <xsd:complexType> </xsd:element> </xsd:schema> //### Z.xsd #### <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xsd:include schemaLocation="A.xsd"/> <xsd:include schemaLocation="B.xsd"/> </xsd:schema>
