| ID | | The ID attribute is a pervasive attribute that uniquely identifies an element within a definition file. The ID needs to be a unique value within the definition. |
| JsonFile | | (Required) The file specification for a Json file. You may enter either a file system location (such as c:\myfolder\mydata.js) or a location from the web (such as http://server/data.js).
