I've already added that, that was giving me a different error. For some
reason it can't create the XML file without that Unrestricted="true" in the
permission set. I'm pretty sure one of IPermissions would be able to control
this. My IPermission for web permission looks like this:

<IPermission
  class="WebPermission"
  version="1">
    <ConnectAccess>
      <URI uri="$OriginHost$"/>
      <URI uri="http://api.google.com/.*"/>
      <URI uri="http://www.google.com/.*"/>
    </ConnectAccess>
</IPermission>
