title: What do the little icons next to the each variable denote, in the SSIS variables window
body: <p>There seems to be variations of the icon image, and i'm sure they mean something. The standard appears to be a blue box with an X in italics. And, some have a little 'circle' in the bottom left of the standard icon image. I have seen a blue circle with an plus in it, a red circle with a plus in it.</p>
  
  <p>what do these mean, and what are the other variations and their meanings.</p>
  
  <p>I have googled a bit and have found no answer.</p>
  
  <p>thanks in advance..</p>
