About extension filtered by privileges

<extension id="vsphere.core.hosts.sampleMonitorView">

  <extendedPoint>vsphere.core.hosts.monitorViews</extendedPoint>

    <object>

       <name>Sample Monitor View Title</name>

       <componentClass className=”com.vmware.vsphere.client.sampleplugin.SampleObjectView”/>

    </object>

  <metadata>

  </metadata>

</extension>

But I don't want to use any system defined privilege. Can I create my own privilege and how to do that?

Thanks,

Selina
