There is no need to have it here.

Also, remove curly braces around {net} to avoid confusion.

Was:
  --empty-ns {net}
                        Create a namespace, but don't restore its properies
                        (assuming it will be restored by action scripts)

Now:
  --empty-ns net        Create a namespace, but don't restore its properies
                        (assuming it will be restored by action scripts)
