SYSML17 — Allocate: Error in operation bodies

The body condition of the Allocate::getAllocatedFrom()
getAllocatedFrom = Allocate.allInstances()->select(to = ref).from
should be
getAllocatedFrom = Allocate.allInstances()->select(supplier = ref).client

to and from are no stereotype or metaclass properties. The appropriate properties are client and supplier defined in the metaclass "Dependency".

Accordingly change the Allocate::getAllocatedTo() body condition as well as the name "getAllocatedFrom" to "getAllocatedTo":

getAllocatedTo = Allocate.allInstances()->select(supplier = ref).client.
