default value for readonly property?

I am creating a colorPalette which is a grid organization of cells with 
the possible colors.   I am giving each cell the role of gridcell since 
the grid is keyboard navigable.  The role spec for gridcell [1] indicates 
that readonly is one of the Inherited States and Properties.  Is this 
inherited from grid since grid is the parent of gridcell?  What is the 
default value of readonly?  I can't find it specified for grid nor in the 
readonly property specification [2]?  Must I always specify the readonly 
state for a grid - I don't see a heading for Required States and 
Properties in the roles specification?

thanks,
-becky
