hi bruce.

The reason for the lack of documentation on this setting is soon Condor will set it correctly automatically, and thus folks need not worry about it.  :).  This should make it into the developer release within 2 weeks.  Setting it manually is a risky business since modifications of the START expression on execute machines could require a change to the schedd SIGNIFICANT_ATTRIBUTES setting.  By having Condor keep this setting correct automatically, we remove a significant burden for pools that span across administrative domains.

Also correct.

Just the schedd I believe.
