+The value of this parameter, if specified, MUST contain a positive integer, where the value "1" represents the highest priority, and subsequent values like "2", "3", and so on, indicate progressively lower priorities. 
+
+To adhere to the definition of a positive integer, the value "0" should not be used as it does not meet the criteria of a positive value. Therefore, any occurrence of "0" as the value for the priority attribute MUST be rejected as invalid.
 
 In the case that this parameter is not specified, the entry will be considered to have a lower priority than all entries which specify any priority.
