+   * - edit-form: /node/{node}/edit
+   * - version-history: /node/{node}/revisions
+   *
+   * These link path patterns are known as entity link relationships and should
+   * be defined using standard templates from the Internet Assigned Numbers
+   * Authority (IANA). A complete listing of IANA URI Template Relationships is
