IFML — Class DomainConcept shoud have multiplicity 0..* with Databinding Class on the model

The way this multiplicity is described on the model does not allow references the same domain concept os different ViewComponents. This way the domain concept on the instances can be referenced only once. The same should be corrected on the diagram 8.18 on page 27.
The validation to guarantee that, for example, two databindings in the same ViewComponent cannot reference the same domain concept should be implemented with other concept than multiplicity.
So dataBinding [0..1]: DataBinding - Reference to the DataBinding in a ViewComponent that uses thecurrent DomainConcept.
Should be replaced by
dataBinding [0..*]: DataBinding - One DomainConcept can be referenced by many databindings. But one Databinding in a ViewComponent should reference only one current DomainConcept.
