RPC get-conf method returned some content not specified by select filter

[nowaits]

Hi olof,
Current netconf RPC get-conf method returned some content not specified by select filter, Below is the test case:

yang:

module example {
    yang-version 1.1;
    namespace "example.com";
    prefix ex;

    container top {
        leaf a {
            type string;
            default "1";
        }
        leaf b {
            type string;
            default "1";
        }
    }
}

config

<configuration>
   <top xmlns="example.com">
      <b>100</b>
   </top>
<configuration>

My calling in netconf is:

<hello
    xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="42">
    <capabilities>
        <capability>urn:ietf:params:netconf:base:1.1</capability>
    </capabilities>
</hello>]]>]]>

<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="42">
    <get-config>
        <source>
            <running/>
        </source>
        <nc:filter nc:type="xpath" nc:select="/top/b" xmlns="example.com"/>
    </get-config>
</rpc>]]>]]>
<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="42"><data><top xmlns="example.com"><a>1</a><b>100</b></top></data></rpc-reply>]]>]]>

In my filter I need 'nc:select="/top/b', but the /top/a also return to me.
It's a bug.
