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