The <input_location> element specifies an address in a format that satisfies the Oracle Spatial and Graph geocoding request XML Schema, which is described in Geocoding Request XML Schema Definition and Example. You can specify the input ___location using either a longitude/latitude pair or the <input_address> element. Example 13-1 in Route Request and Response Examples shows the start and end addresses specified using the <input_location> element and its child element <input_address>.
To use the <input_location> element, you must ensure that the value of the pre_geocoded_locations attribute is FALSE (the default) in the <route_request> element. You can use longitude/latitude pairs and <input_address> elements together in a request.
