Number Case Feature Selector Constants

Some fonts support both lowercase (also called traditional or old-style) numerals, in which some glyphs extend below the baseline, and uppercase (also called lining ) numerals, in which no glyphs extend below the baseline. For fonts that support the number case feature type, you can select either kind of numeral. Table D-17 lists the selectors for this feature.
