/** \ingroup core
* An action scope defines a "place" for an action to be shown and may add
* additional expression variables.
* Each QgsAction can be available in one or several action scopes.
*
* Examples:
* ---------
*
* <dl>
* <dt>Canvas</dt>
* <dd>Show for canvas tools. Adds `@clicked_x` and `@clicked_y` in map coordinates.</dd>
* <dt>Feature</dt>
* <dd>Show in feature specific places like the attribute table or feature
* form.</dd>
* <dt>Field</dt>
* <dd>Show in context menus for individual fields (e.g. attribute table). Adds `@field_index`, `@field_name` and `@field_value`.</dd>
* <dt>Layer</dt>
* <dd>Show in attribute table and work on the layer or selection.</dd>
* </dl>
