key attribute in xml

19
hi,
i created an xml schema with namespace like below.

<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
attributeFormDefault="unqualified" >

but when i use key & keyref, it gives this warning :- "The 'http://www.w3.org/2001/XMLSchema:key' element is not supported in this context."

what can be the problem?

Can anyone please reply....
Thanks in advance.

this is how i specified key :

<xsd:key name="PK_CounterPartyCID" >
<xsd:selector xpath=".//Counter_Party_CID"/>
<xsd:field xpath="CompID"/>
</xsd:key>

just a question, what exactly is the context of your <key> (it's only allowed inside <element>)?
