- * <em>This module, both source code and documentation, is in the\r
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>\r
- * </blockquote>\r
- *\r
- * <p>AttributeList implements the deprecated SAX1 {@link\r
- * org.xml.sax.AttributeList AttributeList} interface, and has been\r
- * replaced by the new SAX2 {@link org.xml.sax.helpers.AttributesImpl\r
- * AttributesImpl} interface.</p>\r
- *\r
- * <p>This class provides a convenience implementation of the SAX\r
- * {@link org.xml.sax.AttributeList AttributeList} interface. This \r
- * implementation is useful both for SAX parser writers, who can use \r
- * it to provide attributes to the application, and for SAX application \r
- * writers, who can use it to create a persistent copy of an element's \r
- * attribute specifications:</p>\r
- *\r
- * <pre>\r
- * private AttributeList myatts;\r
- *\r
- * public void startElement (String name, AttributeList atts)\r
- * {\r
- * // create a persistent copy of the attribute list\r
- * // for use outside this method\r
- * myatts = new AttributeListImpl(atts);\r
- * [...]\r
- * }\r
- * </pre>\r
- *\r
- * <p>Please note that SAX parsers are not required to use this\r
- * class to provide an implementation of AttributeList; it is\r
- * supplied only as an optional convenience. In particular, \r
- * parser writers are encouraged to invent more efficient\r
- * implementations.</p>\r
- *\r
- * @deprecated This class implements a deprecated interface,\r
- * {@link org.xml.sax.AttributeList AttributeList};\r
- * that interface has been replaced by\r
- * {@link org.xml.sax.Attributes Attributes},\r
- * which is implemented in the\r
- * {@link org.xml.sax.helpers.AttributesImpl \r
- * AttributesImpl} helper class.\r
