is currently in the process of being applied to all affected campaigns. This happens right after
adding a policy with "addPolicy".]]>
A campaign's advertiser company is the client company of the corresponding order.
By adding a company filter policy, all existing campaigns owned by that company in its role as advertiser
are assigned to the given filter. New campaigns are assigned automatically to all filters defined by its advertiser's
policies during creation time. By removing a policy all of the advertiser company's
campaigns are removed from that filter. Campaign filter assignments enforced by a campaign advertiser's
policy can not be removed from the campaign as long as the policy exists. This service is stateless.]]>
