Values

Recall that all attributes must have values, even if the value of the attribute is null. Values represent the information that each particular attribute was designed to convey. They carry the “meat” of the information. Values must conform to the attribute type rules outlined previously. Table 2-1 shows examples of each attribute type and the expected value field payload for each.
