only many to one are RTs (Date, Date Time, and Time) to CCT (Date. Time) and RTs (Percent, Rate, and Value) to CCT (Numeric. Type).   I don't think we have a problem here as there is a clear relationship for the two many to one.  We may also find that the new CCTs being proposed - "Video.Type and Sound.Type or e Multimedia.type which also may cover Picture.Type and Graphics.Type would result in adding the RTs we need through a many-to-one relationship.
