ansible.netcommon.netconf_config delete not working and missing example in documentation

[crytectobi]

SUMMARY

I tried to delete configuration from my IOS-XE switch with the ansible.netcommon.netconf_config module.
Pushing configuration is working fine, also commiting is working fine. But how do I delete specific configuration from the switch?
In this example I'm trying to delete the interface description:

    - name: Delete interface description
      ansible.netcommon.netconf_config:
        lock: "never"
        commit: false
        delete: true
        target: candidate
        format: xml
        get_filter: <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native"><interface><GigabitEthernet><name>1/0/2</name></GigabitEthernet></interface></native>
        content: |
          <config xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
            <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native">
              <interface>
                <GigabitEthernet>
                  <name>1/0/2</name>
                  <description></description>
                </GigabitEthernet>
              </interface>
            </native>
          </config>

The results is:
"parameters are mutually exclusive: content|source_datastore|delete|confirm_commit"

So when delete and content are not mutual, how do I define what I want to be deleted?
I also tried this without the delete option:

    - name: Delete interface description
      ansible.netcommon.netconf_config:
        lock: "never"
        commit: false
        target: candidate
        format: xml
        get_filter: <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native"><interface><GigabitEthernet><name>1/0/2</name></GigabitEthernet></interface></native>
        content: |
          <config xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
            <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native">
              <interface>
                <GigabitEthernet>
                  <name>1/0/2</name>
                  <description nc:operation="delete"></description>
                </GigabitEthernet>
              </interface>
            </native>
          </config>

The results is:
XML validation failed with error 'Namespace prefix nc for operation on description is not defined

And since there is no documentation example of the delete option, I don't know how to use this correctly.
Can someone enlighten me and maybe add this to the documentation, if this is not a bug?

One way that I've found we can delete some config with netconf and Ansible it's RPC. You should use other module and pre-built rpc edit-config. To delete description for interface Ansible task will look like this

tasks:
   - name: Delete description
     ansible.netcommon.netconf_rpc:
       rpc: edit-config
       xmlns: urn:ietf:params:xml:ns:netconf:base:1.0
       content: |
         <target>
           <running/>
         </target>
         <config xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0">
           <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native">
             <interface>
               <GigabitEthernet>
                 <name>1/0/2</name>
                 <description nc:operation="remove">test</description>
               </GigabitEthernet>
             </interface>
           </native>
         </config> 

I tried it at another vendor than Cisco, but it worked for me.
