title: Is there any "switch case" in UML use-case specification?
body: <p><strong>Is there any "switch case" in use-case specification?</strong></p>
  
  <p>In the requirements:</p>
  
  <ul>
  <li>When user select "contract" in combobox, a "contract" tab appears, then user will interact with the "contract" tab.</li>
  <li>When user select "Independently funded", a "Funding" tab appears, then user will interact with the "funding" tab.</li>
  </ul>
  
  <p>How can I specify this use-case in my use-case specification? </p>
  
  <p>Those two "case" will be in basic flow, won't they? Then how can I specify the "switch-case"?</p>
  
  <p><strong>Edit:</strong> (Because many mistakes what I'm doing, I will make it clear)</p>
  
  <p>I'm not in progress of drawing use-case or drawing activity diagram, I'm in the between. I'm writing use-case specification (which is used to describe a use-case, and will be used later to draw activity diagram).</p>
