some inconsistencies in the example diagram.txt

[elsdvlee]

The example diagram was important for me to know where to put what info.
However, some inconsistencies lead to confusion.

Example:
class SupplierItemOption {
Item item sc:supportedItem 1
Model predictionModel sc:predictionModel 1
}
SupplierItemOption -- "1" Item
SupplierItemOption -- "1" Model

I think that, in the present implementation only the cardinality mentioned on the link between classes is used.

Can you please review the diagram.txt and leave in only info which is used by the present implementation?
