 In general the sum the real power fractions should be 1.0 and the sum of the reactive power fractions should be less of 0.1.
 
-The `Area` term of the fraction of the `floor_area` affected by the enduse specified.
+The `Area` term of the fraction of the `floor_area` affected by the enduse specified. The default area fraction is `1.0`. The `Electric` term specifies that fraction of the end-use that is electrified. The default is `1.0`.

+In addition, the composition can represent load sensitivities to temperature, price, and occupancy.  The composition parameters are
