title: how to make the json schema flexible enough to handle case sensitive input for enum?
body: <p>Please refer to this question for the introduction <a href="https://stackoverflow.com/q/59963930/11883120">Two way binding dependences based on enum value in json schema</a>.</p>
  
  <p>Now the case is that if I pass <code>userType = CUSTOMER</code> then it doesn't accept the request and in also the case of <code>userType = customer</code>.   </p>
  
  <p>Can anyone suggest me JSON schema solution for this? </p>
