- * wp.media.controller.CollectionEdit
+ * wp.media.controller.Region
  *
- * A state for editing a collection, which is used by audio and video playlists,
- * and can be used for other collections.
+ * A region is a persistent application layout area.
+ *
+ * A region assumes one mode at any time, and can be switched to another.
+ *
+ * When mode changes, events are triggered on the region's parent view.
+ * The parent view will listen to specific events and fill the region with an
+ * appropriate view depending on mode. For example, a frame listens for the
+ * 'browse' mode t be activated on the 'content' view and then fills the region
+ * with an AttachmentsBrowser view.
  *

- * @param {string}                     attributes.title                  Title for the state. Displays in the media menu and the frame's title region.
- * @param {wp.media.model.Attachments} [attributes.library]              The attachments collection to edit.
- *                                                                       If one is not supplied, an empty media.model.Selection collection is created.
- * @param {boolean}                    [attributes.multiple=false]       Whether multi-select is enabled.

- * @param {string}                     attributes.menu                   Initial mode for the menu region. @todo this needs a better explanation.
- * @param {boolean}                    [attributes.searchable=false]     Whether the library is searchable.
- * @param {boolean}                    [attributes.sortable=true]        Whether the Attachments should be sortable. Depends on the orderby property being set to menuOrder on the attachments collection.
- * @param {boolean}                    [attributes.date=true]            Whether to show the date filter in the browser's toolbar.
- * @param {boolean}                    [attributes.describe=true]        Whether to offer UI to describe the attachments - e.g. captioning images in a gallery.

- * @param {boolean}                    [attributes.dragInfoText]         Instructional text about the attachments being sortable.
- * @param {int}                        [attributes.idealColumnWidth=170] The ideal column width in pixels for attachments.
- * @param {boolean}                    [attributes.editing=false]        Whether the gallery is being created, or editing an existing instance.
- * @param {int}                        [attributes.priority=60]          The priority for the state link in the media menu.

- * @param {view}                       [attributes.SettingsView]         The view to edit the collection instance settings (e.g. Playlist settings with "Show tracklist" checkbox).
- * @param {view}                       [attributes.AttachmentView]       The single `Attachment` view to be used in the `Attachments`.

- * @param {string}                     attributes.type                   The collection's media type. (e.g. 'video').
