The sense of owned ends in this example is in contrast to:
In the example below the «connection def» ProductSelection has unnamed owned cross features of type ShoppingCart and Product respectively (which have implied featuring by the types of their respective crossed ends).
Although not further used in the example, «connection def» ProductSelection1 has named owned cross features inCart and selectedProducts.
Note that connection ps1 does not have implied cross subsettings or cross features:
connection ps1 : ProductSelection connect myCart to products {
:>> info = info1;
}Whereas connection ps2 DOES have implied cross subsettings and implied cross features:
connection ps2 : ProductSelection connect [1] myCart to [1] products {
:>> info = info1;
}It's not so clear what the purpose of
SingleProductSelection and SingleProductSelection1 are in the sample if they aren't used.
