EXPRESS_ — Delete associations to Instance classes in 12.10

In 12.10 PartialEntityConstructor, Figure 41, the AttributeValue, SingleEntityValue, and PartialEntityValue objects are the result of evaluating the constructor at a particular runtime instant. They should not be part of this model - the results of other operations are not modeled. The associations that reflect runtime evaluation - AttributeBinding:to-value, and PartialEntityConstructor:result-value should be deleted from the model. (Some such diagram could be used to explain what is happening, but it would be descriptive, not normative. Or these relationships could be shown as some kind of stereotyped dependency.)

AttributeBinding:to-value should not be part of the model, and it isn’t documented; it only appears in Figure 41. And the use of AttributeValue and SingleEntityValue in the diagram are inappropriate.
PartialEntityConstructor:result-value provides a means of linking a constant value to the constructor Expression when appropriate – it subsets Expression:evaluation.
