/**
 * Defines a data type attribute.
 *
 * The typed data API allows modules to support any kind of data based upon
 * pre-defined primitive types and interfaces for complex data and lists.
 *
 * Defined data types may map to one of the pre-defined primitive types below
 * \Drupal\Core\TypedData\Type or may be complex data types, containing
 * one or more data properties. Typed data objects for complex data types have
 * to implement the \Drupal\Core\TypedData\ComplexDataInterface. Further
 * interfaces that may be implemented are:
 *  - \Drupal\Core\Access\AccessibleInterface
 *  - \Drupal\Core\TypedData\TranslatableInterface
 *
 * Furthermore, lists of data items are represented by objects implementing the
 * \Drupal\Core\TypedData\ListInterface. A list contains items of the same data
 * type, is ordered and may contain duplicates. The class used for a list of
 * items of a certain type may be specified using the 'list class' key.
