Editing Data Files

In the VehicleSize data file, it has the following:
Requirement X Type:
Specific Component - Must have, Specific Component - Cannot have, General Type - Have exactly,
General Type - Cannot have, General Type - Min Percent, General Type - Max Percent,
General Type - Min Amount, General Type - Max Amount, Custom Group - Cannot have,
Custom Group - Have exactly, Custom Group - Min Percent, Custom Group - Max Percent,
Custom Group - Min Amount, Custom Group - Max Amount, Ability - Cannot have,
Ability - Have exactly, Ability - Min Percent, Ability - Max Percent,
Ability - Min Amount, Ability - Max Amount

How exactly do I go about incorporating these modifiers? For example, I want to create a Ringworld platform specifically designed for holding HD Cables with the requirement MUST HAVE HD CABLES, but I can't seem to create the Requirement line correctly for SEIV to accept. Any pointers?
