/**
 * Sets {@link Relation.expandForDescription} for a resource.
 *
 * For example, we'll use a `Student` resource from
 * [Getting Started Tutorial](/docs/Documentation/GettingStarted#resource-relations)
 * with a related `Teacher` resource.
 *
 * Each Student row contains only the teacher reference (for example, the teacher's id).
 * When {@link expandDescription} is applied to the Teacher field, the Student output will include
 * additional textual properties from the related Teacher object (for example,  teacher's name,
 * title or other descriptive fields).
 *
 * **Before applying the decorator:**
 *
 * | Student Name |
 * |--------------|
 * | Alice        |
 * | Bob          |
 * | Charlie      |
 * | Dana         |
 *
 * **After applying {@link expandDescription} to the Teacher field in Student resource:**
 *
 * | Student Name | Teacher |
 * |--------------|---------|
 * | Alice        | John    |
 * | Bob          | Mary    |
 * | Charlie      | Emma    |
 * | Dana         | Frank   |
 *
 * Sets `{@link PropertyMeta.expandDescription}`.
