// Description:
// ContentLocatorGroup represents a set of Locators. This is used to
// model an anchor that is made up of several separately identifiable
// pieces such as a set of Visio objects.
//
// Spec: http://team/sites/ag/Specifications/Simplifying%20Store%20Cache%20Model.doc
//
// History:
// 11/10/2003: rruiz: Created class and file.
// 12/03/2003: ssimova: Changed LocatorParts to Parts
// 12/09/2003: ssimova: Added Id property
// 03/02/2004: rruiz: Renamed the class to LocatorGroupImpl from RangeLocatorImpl
// 06/30/2004: rruiz: Reworked the API of the class to be more direct (such as
// no longer having a Parts property), added support for
// notifications to its owner and from its sequences.
