+ * Provides an interface for an Action plugin.
+ *
+ * @todo WARNING: The action API is going to receive some additions before
+ * release. The following additions are likely to happen:
+ * - The way configuration is handled and configuration forms are built is
+ * likely to change in order for the plugin to be of use for Rules.
+ * - Actions are going to become context-aware in
+ * https://www.drupal.org/node/2011038, what will deprecated the 'type'
+ * annotation.
+ * - Instead of action implementations saving entities, support for marking
+ * required context as to be saved by the execution manager will be added as
+ * part of https://www.drupal.org/node/2347017.
+ * - Actions will receive a data processing API that allows for token
+ * replacements to happen outside of the action plugin implementations,
+ * see https://www.drupal.org/node/2347023.
