iStartOn = break-before?

[Glen Mazza]

Team,
The AbstractBreaker.BlockSequence has an "iStartOn" property, that from 
looking at PSLM, quite possibly just means the "break-before" trait.  
Are they synonyms?  I would like us to use the official Rec term if at 
all possible.

Thanks,
Glen

       private int startOn;
       public BlockSequence(int iStartOn) {
           super();
           startOn = iStartOn;
       }
