Extension from an external module in a different namespace

[SpaceCowboy850]

I'm doing some code generation, and for coding reasons, I want to derive from the same base type for all of my XSDs.

 

So this works:

 

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" version="1.02"> <xs:include schemaLocation="MessageBase.xsd"/> <xs:element name="ServiceRequest" type="ServiceRequestType_VersionInfo_Request"/> <xs:complexType name="ServiceRequestType_VersionInfo_Request" mixed="true"> <xs:complexContent> <xs:extension base="MessageBase">

 

<!-- insert schema definition stuff here --> </xs:extension> </xs:complexContent> </xs:complexType></xs:schema>

In another file, I have this:

 

<?xml version="1.0" encoding="UTF-8"?><!-- edited with XMLSPY v2004 rel. 3 U (http://www.xmlspy.com) by VeriFone, Inc. (VeriFone, Inc.) --><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" version="2.5"> <xs:complexType name="MessageBase"/></xs:schema>

 

But I need that first file in its own namespace. If i set a "targetNamespace" on the first file (to put it in its own namespace), then it complains it can't find the MessageBase complexType. I'm not sure what I'm doing wrong.

 

Any ideas?
