It is recommended you load the atgsvcs library by using a page tag included in either the head or the body of each page. This ensures that the library is loaded before the DOMContentLoaded event is fired by the browser, and so we can use the DOMContentLoaded event to trigger the Rules Request for the page.

If you do not load the atgsvcs library by including a page tag you can load it dynamically by calling atgsvcs.start() to trigger the Rules Request for the page.
