FundamentalProfile is a self-validating FDO profile. It serves as a base case for the recursive definition of FDO profiles. (Per FDO specifiction, every FDO record must conform to an FDO profile, and every FDO profile is represented by an FDO record.) In other words, FundamentalProfile is designed such that every valid FDO profile conforms to FundamentalProfile, including FundamentalProfile itself.
