For example, I have 2 Xml schemas:
<xsd:schema xmlns:xsd="" xmlns="test" targetNamespace="test">
    <xsd:include schemaLocation="b.xsd" />

<xsd:schema xmlns:xsd="">
    <xsd:simpleType name="testType">
        <xsd:restriction base="xsd:string">
            <xsd:enumeration value="test"/>
    <xsd:element name="test" type="testType"/>

Second schema does not have targetNamespace and used as a chameleon schema.
I am trying to pre-load these schemas using .Net XmlSchemaSet:

XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.Add(null, @"a.xsd");
foreach (XmlSchema schema in schemaSet.Schemas())  // foreach is used to simplify the example
    Console.WriteLine("Target namespace: "schema.TargetNamespace);  // "Target namespace: test"
    XmlSchemaInclude include = (XmlSchemaInclude)schema.Includes[0];
    Console.WriteLine("Include target namespace: " + include.Schema.TargetNamespace); // "Include target namespace: test"

But after I do it both schemas have "test" target namespace. I expect instantiated schema objects should be equal to source schemas, but it is not true for schema "b.xsd". Why it behaves so and is there any way to disable such a behavior?

You didn't set a targetnamespace in b.xsd, so the targetnamespace from a.xsd is used.
Try to give b.xsd a different targetnamespace than a.xsd and the b.xsd xmlschema should have a different one.

I dont want to make any changes in original schemas. Here is the expecting behaviour:
I open b.xsd using some api(XmlSchemaSet used for this) , serealize loaded schama objects to the custom binary format, deserealize data to xsd. After the last step i am expect that output xsd`s will be the same as original, but targetNamespace was added. A can manualy load schemas, but there are many worst cases, so i am loking for existing solution at first. Maybe schemaSet is a wrong choise.
