To declare a policy
Add a <policy> childelement to the <policies> element.
Set the Id attribute of the <policy> element to the name of the policy.
The Id attribute must conform to the ID attribute as defined in the XML 1.0 recommendation. Specifically, the name begins with a letter or underscore and continues with name characters (letters, digits, and other characters) and must be unique to the policy file.
Add one or more requirements to the policy assertion.
