We have to make some choices when we dimension a block with a notch or cutout. It is usually best to dimension from a common line or surface. This can be called the datum line of surface. This eliminates the addition of measurement or machining inaccuracies that would come from "chain" or "series" dimensioning.
any level surface from which vertical distances of the points above or below this surface are measured is known as datum
a theoretically exact point, axis, or plane derived from the true geometric counterpart of a specified datum feature. A datum is the origin from which the location or geometric characteristics of features of a part are established.

No, then it would not be a reference dimension. Reference dimensions by definition have no tolerance.
