The Annotations topic should document that some annotation types, which extend the PluginID annotation class, have only a single 'id' key in their annotation. For these, it is possible to use a shorthand annotation:
* @SimplePluginType("id_value")in place of
* @SimplePluginType(
* 'id' => "id_value"
* )Task: Add this information to the topic, which is located in the file core/modules/system/system.api.php near the end (although the topic documentation may soon be moved to file core.api.php).
Note that you need to leave a space after the @ sign, as is done in the rest of this documentation.
