4172//	2. Improve the module's maintainability by reducing the storage
4173//		paths to a single mechanism.
4174//	3. Use the same single mechanism to support "private" and "user" data.
4175//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
4176//	5. Avoid exposing implementation details on user objects (eg. expando properties)
4177//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

10381// way to register. Lowercase jquery is used because AMD module names are
10382// derived from file names, and jQuery is normally delivered in a lowercase
10383// file name. Do this after creating the global so that if an AMD module wants
10384// to call noConflict to hide this version of jQuery, it will work.

10387// declare themselves as anonymous modules, and avoid setting a global if an
10388// AMD loader is present. jQuery is a special case. For more information, see
