DNI and 0 Ohms Resistors

I have recently been re-creating the BB-xM (RevA3) schematics. Through
the design process I have come across a large number of components
listed as "DNI" or "Do Not Inlcude" in the design. Along those same
lines, there is a significant amount of 0 ohm resistors in the design
as well. How should I handle these components for a production board?
Should they be ignored and removed from the design, or should they be
included "just in case" on the final design?
