Chris@0: Code in the Drupal\Core namespace represents Drupal Subsystems provided by the
Chris@0: base system.  These subsystems MAY depend on Drupal Components and other
Chris@0: Subsystems, but MAY NOT depend on any code in a module.

Chris@0: Each Subsystem should be in its own namespace, and should be as self-contained
Chris@0: as possible.
