  # From: http://code.google.com/apis/adwords/v2009/docs/reference/AdGroupAdService.MobileAd.html
  #   A mobile ad can contain a click-to-call phone number, a link to a website, or both.
  #   You specify which features you want by setting certain fields, as shown in the following table.
  #   For example, to create a click-to-call mobile ad, set the fields in the Click-to-call column.
  #   A hyphen means don't set the corresponding field.
