Number Case Feature Type

The number case feature type (kNumberCaseType) specifies whether to use numerals that extend below the baseline. Figure B-14 shows both kinds of numerals. Lowercase numerals (also called traditional or old-style) may descend below the baseline, as shown in the bottom line of the figure. Uppercase numbers (also called lining) do not descend below the baseline.
