copy-config: accepting same target as source

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Connect to server.
2. Send message with equal source and target datastore, for example:
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="35">
  <copy-config>
        <source>
                <candidate/>
        </source>
        <target>
                <candidate/>
        </target>
</copy-config>
</rpc>


What is the expected output?
If the <source> and <target> parameters identify the same URL or
configuration datastore, an error MUST be returned with an error-
tag containing "invalid-value". [RFC6241]

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="35">
  <rpc-error>
    <error-tag>invalid-value</error-tag>
    <error-type>protocol</error-type>
    <error-severity>error</error-severity>
    <error-message>The request specifies an unacceptable value for one or more parameters.</error-message>
  </rpc-error>
</rpc-reply>

What do you see instead?

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="35">
  <ok/>
</rpc-reply>
