Hi, i tried adding metadata to Network XML ( NOT DOMAIN XML) but it removes it as soon as i save

 here's my network XML

<network>

  <name>bridgeTest0</name>

  <uuid>cf2aae7a-b459-459b-ba2c-399190607629</uuid>

  <metadata>

        <app1:foo xmlns:app1="http://app1.org/app1/">

                <app1:test>testing!</app1:test>

        </app1:foo>

  </metadata>

  <forward mode='bridge'/>

  <bridge name='lxcbr0'/>

</network>
