title: What is the 'criticality' attribute in SimplePagedResultsControl in python-ldap?
body: <p>I'm using python-ldap for pagination of LDAP search.<br>
  I found many similar references online and all of them set:<br>
  <code>page_control = SimplePagedResultsControl(True, size={some_size}, cookie='')</code><br>
  For example: <a href="https://medium.com/@alpolishchuk/pagination-of-ldap-search-results-with-python-ldap-845de60b90d2" rel="nofollow noreferrer">https://medium.com/@alpolishchuk/pagination-of-ldap-search-results-with-python-ldap-845de60b90d2</a><br>
  I checked python-ldap's documentation and couldn't find a useful explanation:<br>
