| AllowUnknownMessageFields | CheckUserDefinedFields | Field | Validation |                                                            Exception | 
+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+ 

1) GOOD. Field 1000 is NOT a user field so it should SUCCEED when AllowUnknownMessageFields == true

+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+

2) BAD. Field 6000 is a user field so it should FAIL when CheckUserDefinedFields === true

+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+                       
|                     false |                  false |  6000 |    SUCCESS |                                                                      |

+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+

3) BAD. Field 2000 is NOT a user field so it should SUCCEED when AllowUnknownMessageFields == true (even though it's not inside <fields> tag)

+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+

+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+

4) GOOD. Field 7000 is a user field so it should SUCCEED when CheckUserDefinedFields == false

+---------------------------+------------------------+-------+------------+----------------------------------------------------------------------+
|                     false |                  false |  7000 |    SUCCESS |                                                                 	 |
