/**
 * Enumeration for localized messages formats used in exceptions messages.
 * <p>
 * The constants in this enumeration represent the available
 * formats as localized strings. These formats are intended to be
 * localized using simple properties files, using the constant
 * name as the key and the property value as the message format.
 * The source English format is provided in the constants themselves
 * to serve both as a reminder for developers to understand the parameters
 * needed by each format, as a basis for translators to create
 * localized properties files, and as a default format if some
 * translation is missing.
