Instances don't need to be inline...
This instance loads its data from a local file. However this can be any kind of URL.
Just note the syntax to access JSON values. XPath 3.1 notation is used to query the JSON.
Notice that we've called this demo with 2 parameter on the querystring of the URL. When using the constant
#querystring as the src of an instance it will created a instance with one node for
each param on the querystring.
