  16 // The new kind of Chrome app/extension permission messages.
  17 //
  18 // A PermissionMessage is an immutable object that represents a single bullet
  19 // in the list of an app or extension's permissions. It contains the localized
  20 // permission message to display, as well as the set of permissions that
  21 // contributed to that message (and should be revoked if this permission is
  22 // revoked). It can also optionally contain a list of sub-messages which should
  23 // appear as nested bullet points below the main one.
  24 //
  25 // |permissions| contains the permissions that are 'represented' by this
  26 // message and should be revoked if this permission message is revoked. Note
  27 // that other permissions could have contributed to the message, but these are
  28 // the ones 'contained' in this message - if this set is taken for all
  29 // PermissionMessages, each permission will only be in at most one
  30 // PermissionMessage.
  31 //
  32 // Some permissions may contain nested messages, stored in |submessages|. These
  33 // are appropriate to show as nested bullet points below the permission,
  34 // collapsed if needed. For example, host permission messages may list all the
  35 // sites the app has access to in |submessages|, with a summary message in
  36 // |message|.
  37 //
  38 // TODO(sashab): Add a custom revoke action for each permission and nested
  39 // permission message, registerable as a callback.
