title: does input validation fits into detailed use case description?
body: <p>Suppose I am developing a web application. Now, I have a form where user need to fill in the form where the form contains both client side and server side validation. Does this validation fits into detail use case description? if not, where should it generally fit into a system document report?</p>
  
  <p>Note: Server side validation does not necessary fits to database schema <br />
  Example: database column can contain maximum 10 characters but validation allow user enter 6 characters only</p>
