---------------------------------------------------------------

In an expression like: Customers?$filter=Orders($filter=ShipTo eq @a)&@a=City

Is City the city property of the customer or the order?

I would have assumed it's the city of the customer, but if we are replacing the parameter with the expression doesn't it become the city of the Order? That would be very confusing...

> 11.2.6.1.3 Parameter Aliases specifies that "Parameter aliases allow the same value to be used multiple times in a request and may be used to reference primitive values, complex, or collection values" yet in both Example 67 and Example 79 we ourselves show that aliases can also be used to substitute expressions, something which my developers deem is against what's been specified in 11.2.6.1.3, hence the ask for clarification.
