title: Explanation of arrows in RTC flow diagram
body: <p>In below diagram what is the meaning of below arrows ?</p>
  
  <p>Here's what I think : 
  Each arrow describes where the change sets are flowing from/to. So the top workspace flows changes and accepts changes from the stream. The bottom two workspaces just flow changes to the stream, theses workspaces do not accept any changes from the stream. Is this correct ?</p>
  
  <p>What is the meaning of the broken blue arrow ?</p>
