 ## Limitations
 
 * CBOR tags (type 6) are ignored.  Decoder simply decodes tagged data after ignoring the tags.
-* CBOR negative int (type 1) that cannot fit into Go's int64 are not supported.  So RFC 7049 test data -18446744073709551616 is skipped.
+* CBOR negative int (type 1) that cannot fit into Go's int64 are not supported, such as RFC 7049 test data -18446744073709551616.  Decoding these values returns `cbor.UnmarshalTypeError`.
+* CBOR `undefined` value (0xf7) decodes to Go's `nil` value.  However, Go's `nil` value encodes to CBOR `Null` value (0xf6).
