-| ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------ |
-| Input             | A relational input, typically with a desired orderedness property.                                                                                                                                 | Required                 |
-| Offset Expression | An expression which evaluates to a non-negative integer (recommended type is `i64`). Declares the offset for retrieval of records.                                                                 | Optional, defaults to 0. |
-| Count Expression  | An expression which evaluates to a non-negative integer or -1 (recommended type is `i64`). Declares the number of records that should be returned. -1 signals that ALL records should be returned. | Required                 |
+| Property          | Description                                                                                                                                                                                                                          | Required                   |

+| Offset Expression | An expression which evaluates to a non-negative integer or null (recommended type is `i64`). Declares the offset for retrieval of records. An expression evaluating to null is treated as 0.                                         | Optional, defaults to 0.   |
+| Count Expression  | An expression which evaluates to a non-negative integer or null (recommended type is `i64`). Declares the number of records that should be returned. An expression evaluating to null indicates that all records should be returned. | Optional, defaults to all. |
