    Accept and Content-type are both headers sent from a client (a browser) to a service.
    Accept header is a way for a client to specify the media type of the response content it is
    expecting and Content-type is a way to specify the media type of request being sent from the
    client to the server.
    The response was sent in XML so we can say the Accept header sent was application/xml.

    Tested using Postman.
    When using application/xml on the Accept Header (HTTP 400 Bad Request):
    {
    "errors": {
    "error": [
    {
    "error-message": "mismatched keypaths: /interface , /if:interfaces",
    "error-path": "/ietf-interfaces:interfaces",
    "error-tag": "malformed-message",
    "error-type": "application"
    }]}}

    When using application/xml on the Content-Type Header (HTTP 415 Unsupported Media Type):
    {
    "errors": {
    "error": [
    {
    "error-message": "Unsupported media type: application/xml ; Should be one of: application/yang-data+xml, application/yang-data+json.",
    "error-tag": "malformed-message",
    "error-type": "application"
    }]}}
