How to pass Schema in Postman for XML Responses?

Question

I have received Successful response for a SOAP Post Request in Postman which is well explained in this link. But I want to know how can I pass the Schema for XML responses by the Snippet: Use tiny validator for json data which is used often to validate JSON Schema.

Endpoint: https://www.w3schools.com/xml/tempconvert.asmx

Body:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
   <FahrenheitToCelsius xmlns="https://www.w3schools.com/xml/">
     <Fahrenheit>100</Fahrenheit>
   </FahrenheitToCelsius>
  </soap:Body>
</soap:Envelope>

Response:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <FahrenheitToCelsiusResponse xmlns="https://www.w3schools.com/xml/">
            <FahrenheitToCelsiusResult>37.7777777777778</FahrenheitToCelsiusResult>
        </FahrenheitToCelsiusResponse>
    </soap:Body>
</soap:Envelope>
