|I'm not sure I follow the argument. The text says:
|
|    The first column of the rules [after LOC] defines the CFA rule...
|    
|    The remaining columns are labeled by register number...

Ahhhh.  Quite.  I erroneously thought there was only
one interpretation!  Now I understand at least a second interpretation :-)

So we do need a clarification as you suggested.
