> Part 2 section 4.3.3 allows omitting key values that are implicitly specified by referential constraints to key values provided in previous path segments:
> https://host/service/Orders(1)/Items(OrderID=1,ItemNo=2)
> https://host/service/Orders(1)/Items(2)
> The shorter form is preferred for parentheses-key syntax, and both are allowed.
> We cannot give that choice for key-as-segment style because the number and order of path segments must be deterministic, so it is either
> https://host/service/Orders/1/Items/1/2
> or
> https://host/service/Orders/1/Items/2
> Shorter is better, so it must be the second.
