<key> problems.

I'm trying to impliment a <key> as below but for some reason it
doesn't work. Is it me that's wrong, or XMLSpy 4.1?

I have a document like this:

<IDs>
    <Form FormID="1">
        <Field FieldID="1"/>
    </Form>
    <Form FormID="2">
        <Field FieldID="1"/>
    </Form>
</IDs>

In the Schema I have the following KEY on the <IDs> element:

<xs:key name="FieldsByFormKey">
    <xs:selector xpath="Form/Field"/>
    <xs:field xpath="../@FormID"/>
    <xs:field xpath="@FieldID"/>
</xs:key>

I believe this document should be valid against that Key constraint,
but XMLSpy4.1 says that the second <Field> element produces a
duplicate Key value, and hence is invalid.

By my understanding there should be two unique keys generated:
 {1 1) (2 1}

So, it is me or XMLSpy at fault?
