update change with whereParam

1.         <update tableName="PERSON">
2.             <column name="BIRTHDATE" value="1942" type="NUMBER(4)"/>
3.             <whereParams>
4.                 <param name="ID" value="1"/>
5.             </whereParams>
6.         </update>

1. Caused by: liquibase.exception.ValidationFailedException: Validation Failed:
2.      1 changes have validation failures
3.           whereParams set but no whereClause,

What's the appropriate syntax?
