title: What does the number after //$NON-NLS- mean
body: <p>This is a follow up question to: <a href="https://stackoverflow.com/questions/654037">What does $NON-NLS-1$ mean?</a></p>
  
  <p>I've noticed that the comment tag will be recognized as a NLS tag when you use any number. However, only the number 1 seems to correctly fixed the warning. (Silenced warning vs. unsilenced warning + unnecessary nls tag)</p>
  
  <p>What is the purpose of this?</p>
