A Value Object may possess just one, a few, or a number of individual attributes, each of which is related to the others. Each attribute contributes an important part to a whole that collectively the attributes describe. Taken apart from the others, each of the attributes fails to provide a cohesive meaning. Only together do all the attributes form the complete intended measure or description. This is different from merely grouping a set of attributes together in an object. The grouping itself accomplishes little if the whole fails to adequately describe another thing in the model.
