title: can query parameters be mandatory in REST API
body: <p>I have a requirement which says there has to be two parameters(one of them represents date) that are part of the GET URI have to be mandatory. But these two parameters are only for filtration purpose. So my question is,
  <strong>Can mandatory parameters be used as Query params?</strong> (Or we can still use them as path params although there is no parent/child relationship)</p>
