### Issue details

Using the code provided in the documentation:

```
response = client.express_route_cross_connections.begin_create_or_update(
resource_group_name="CrossConnection-SiliconValley",
cross_connection_name="",
parameters={"properties": {"serviceProviderProvisioningState": "NotProvisioned"}},
).result()
```

results in the following error:

raise HttpResponseError(response=response, error_format=ARMErrorFormat)
azure.core.exceptions.HttpResponseError: (LocationRequired) The location property is required for this definition.
Code: LocationRequired
Message: The location property is required for this definition.

Turns out the code needs "location" and expressRouteCircuit parameters to work correctly, so a working example would look like this:

```

response = client.express_route_cross_connections.begin_create_or_update(
resource_group_name="CrossConnection-SiliconValley",
cross_connection_name="",
parameters={"serviceProviderProvisioningState": "NotProvisioned",
"location": expressroute.location,
"expressRouteCircuit": {
"id": expressroute.express_route_circuit.id
}},
).result()
```

where expressroute is the ExpressRouteCrossConnect object being updated as returned from express_route_cross_connections.get() method

### Expected behavior

expected behavior is for the example code to work (ie, not return any errors from the API) and result in the serviceProviderProvisioningState being updated to the given value.

### Actual behavior

throws an error:

raise HttpResponseError(response=response, error_format=ARMErrorFormat)
azure.core.exceptions.HttpResponseError: (LocationRequired) The location property is required for this definition.
Code: LocationRequired
Message: The location property is required for this definition.

### Reproduction Steps
