  *
  * then if the field mask is:
  *
- *  paths: "f.b"
+ *  paths: ["f.b", "f.c"]

  *       }
- *       c : 1
+ *       c: [1, 2]
  *     }
  *
- * However, if the update mask was:
- *
- *  paths: "f.b.d"
- *
- * then the result would be:
- *
- *     f {
- *       b {
- *         d : 10
- *         x : 2
- *       }
- *       c : 1
- *     }
+ * An implementation may provide options to override this default behavior for
+ * repeated and message fields.
  *
  * In order to reset a field's value to the default, the field must
  * be in the mask and set to the default value in the provided resource.
