True. What I wanted was to differentiate map that is defined in the register definition and other maps to which this default map is added(in a wrapper outside the reg_top).
The reg_model defines the structure of your registers in the DUT. This register model might contain sub_maps as required by the structure in the DUT.
But you cannot have a reg_map outside of your top reg_block (register model).
