/**
 * Sets attributes on the destination.
 *
 * The attribute name is constructed during the migration, it is prepended with
 * 'attribute_' and the length checked. Since the name is not known beforehand
 * the destination for the attribute values on the product variation is set by
 * this process plugin.
 *
 * The input is a array of values, in pairs. The first element is the array
 * output from 'import_attribute', which supplies the verified name. The second
 * element is the value of the attribute.
 *
 * Example:
 *
 * @code
 * process:
 *   anyname:
 *     plugin: csv_example_attribute_destination
 *     source:
 *       - attribute1_name
 *       - attribute1_value
 *       - attribute2_name
 *       - attribute2_value
 * @endcode
 *
 * If attribute1_name is 'color', attribute_1_value is 'green', attribute2_name
 * is 'size' and attribute2_name is 'Med' then destination property 'color' is
 * set to 'red' and destination property 'size' is set to 'Med'.
 *
 * @throws \Drupal\migrate\MigrateException
 *   Thrown when there is not an even number of elements in the input array.
 *
 * @MigrateProcessPlugin(
 *   id = "csv_example_attribute_destination"
 * )
