 Here's an example response with two missing parameters. The `software_id`
 validation callback returns a `WP_Error` instance, while the
 `software_version` is required, but doesn't have a validation callback
 defined.

 {{{
 {
    "code":"rest_invalid_param",
    "message":"Invalid parameter(s): software_id (Invalid software
 identifier.), Invalid parameter.",
    "data":{
       "status":400,
       "params":{
          "0":"software_id (Invalid software identifier.)",
          "software_version":"Invalid parameter."
       }
    }
 }
 }}}
