is it a bug,or i m wrong?

[=?gb2312?B?ZmNft72zrA==?= <fangc@bsoft.com.cn>]

Hi

I had a post in 2003-4-29, said I m could import a abstract complex type and derived from that complex type. And thanks Mr. Henry S. Thompson, he give me the advice that I use the same target namespace in import file.
Well, after I using the different target Namespace, the problem still exists.
I could not find any mistake I have made in the file. So I think maybe it's the parser's bug,and I fix the MSXML 4.0 Service Pack 2,but the issue still occur.
What could I do?
This problem has tortured me for a whole week.
Is it a bug? Or are these file correct?
Could anyone help me?

Here is the file.
main.xsd
<xs:schema targetNamespace="http://www.test.com/"; xmlns="http://www.test.com/";  xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified">
	<xs:simpleType name="PowerEnum">
		<xs:restriction base="xs:string">
			<xs:enumeration value="1Pounds"/>
			<xs:enumeration value="2Pounds"/>
			<xs:enumeration value="300Pounds"/>
		</xs:restriction>
	</xs:simpleType>
	<xs:complexType name="Man" abstract="true">
		<xs:sequence>
			<xs:element name="Name" type="xs:string"/>
			<xs:element name="Power" type="PowerEnum"/>
		</xs:sequence>
	</xs:complexType>
</xs:schema>

main_derive.xsd
<xs:schema xmlns="http://www.test.com/ok"; targetNamespace="http://www.test.com/ok"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:im="http://www.test.com/"; elementFormDefault="qualified">
	<xs:import namespace="http://www.test.com/"; schemaLocation="main.xsd"/>
	<xs:complexType name="SuperMan">
		<xs:complexContent>
			<xs:restriction base="im:Man">
				<xs:sequence>
					<xs:element name="Name" type="xs:string"/>
					<xs:element name="Power">
						<xs:simpleType>
							<xs:restriction base="im:PowerEnum">
								<xs:enumeration value="300Pounds"/>
							</xs:restriction>
						</xs:simpleType>
					</xs:element>
				</xs:sequence>
			</xs:restriction>
		</xs:complexContent>
	</xs:complexType>
	<xs:element name="test">
		<xs:complexType>
			<xs:sequence>
				<xs:element name="OneMan" type="SuperMan"/>
				<xs:element name="ok" type="xs:string"/>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
</xs:schema>

what could I do?
I check the file for hundreds of times. But no miracle happened. How depress I was!
Best Regards

You're using import for a schema document with the same target
namespace as the importing document -- you should be using include.

See the W3C XML Schema Primer [1] for an example.
