You have been tasked to develop a solution that will notify an external system when...

Define a new “notify” aspect with a “multi” peer association. Create and register a policy behavior that, when content is updates, users can associate their content via this aspect. As associations are being made, the external notification request will be triggered.

Define a new “notify” aspect with no properties. Create and register a policy behavior that, if this aspect is present, will make the external notification request. Users can simply add this aspect to their content item.

Extend cm:content to provide an additional “notify” property. Create a policy behavior that will look at the “notify” property and, if set, make the external notification request. Users simply create cm:content items.

Extend sys:base to provide an additional “notify” property. Create a new policy that will look at the “notify” property and, if set, make the external notification request. Users can simply call an action against their content item.
