In the above, the "customer" variable is an external variable. The key for the
external variable is derived from the value of the `customerid` element in the
"order" variable. Note that the "order" variable must be declared in a scope
above the scope declaring the "customer" external variable, otherwise it would
not be possible to resolve the identify of the "customer" variable. In this
scenario, the external variable can be "read" even if it was never assigned to
in the process.
