Value Class - If a data type of the type Object is chosen, the path to a class that defines the Java type associated with the value is entered here. Value - The value of the data element. Only values that agree with data type chosen in Value Type can be entered. If the value type is an object, the Value is a string that represents a value of the type in the Value Class.
	Array - An array is defined, where the values in the array can be of any of the data types supported by ERE.	Array Values - An array editor, in which the array of values for the element is entered. Only values that agree with data type chosen in Value Type can be entered.

A new data element is added to the service by using the Add button. A data element is removed from the service by using the Delete button.

An existing data element can be edited by selecting the element from the Data Element list. If a data element is entered with an invalid format or incomplete information, a pop-up appears with an error message when Commit is chosen.

The changes are discarded and the old values retained when the Cancel button is chosen.

The changes are first implemented in the service when the service is saved.
