 * This class provides a default implementation of the SAX2 Attributes
 * interface, with the addition of manipulators so that the list can
 * be modified or reused.
 *
 * There are two typical uses of this class:
 *
 * - to take a persistent snapshot of an Attributes object in a
 *   startElement event; or
 * - to construct or modify an Attributes object in a SAX2 driver or filter.
 *
 * This class replaces the now-deprecated SAX1 AttributeListImpl
 * class; in addition to supporting the updated Attributes interface
 * rather than the deprecated AttributeList interface, it also
 * includes a much more efficient implementation using a single array
 * rather than a set of Vectors.
