public class Categories
extends Object

Data for Regular expression character categories. The data is in an XML file derived from the Unicode database (In Saxon 9.6, this is based on Unicode 6.2.0). Since Saxon 9.4, we no longer make use of Java's support for character categories since there are too many differences from Unicode.
