* <p>AttributeList implements the deprecated SAX1 {@link

*
* <p>This class provides a convenience implementation of the SAX
* {@link org.xml.sax.AttributeList AttributeList} interface. This
* implementation is useful both for SAX parser writers, who can use
* it to provide attributes to the application, and for SAX application
* writers, who can use it to create a persistent copy of an element's
* attribute specifications:</p>
*
* <pre>
* private AttributeList myatts;
*
* public void startElement (String name, AttributeList atts)
* {
* // create a persistent copy of the attribute list
* // for use outside this method
* myatts = new AttributeListImpl(atts);
* [...]
* }
* </pre>
*
* <p>Please note that SAX parsers are not required to use this
* class to provide an implementation of AttributeList; it is
* supplied only as an optional convenience. In particular,
* parser writers are encouraged to invent more efficient
* implementations.</p>
*
* @deprecated This class implements a deprecated interface,
* {@link org.xml.sax.AttributeList AttributeList};
* that interface has been replaced by

* prefix/URI mapping is repeated for each context (for example), this
* class will be somewhat less efficient.</p>

*
* <li>If the system property <code>org.xml.sax.driver</code>
* has a value, that is used as an XMLReader class name. </li>
*
* <li>The JAR "Services API" is used to look for a class name
* in the <em>META-INF/services/org.xml.sax.driver</em> file in

*
* <li> SAX parser distributions are strongly encouraged to provide
* a default XMLReader class name that will take effect only when
* previous options (on this list) are not successful.</li>
*
* <li>Finally, if {@link ParserFactory#makeParser()} can
* return a system default SAX1 parser, that parser is wrapped in

* initialized on a command line. This means that <em>in most cases</em>
* setting a good value for that property ensures that calls to this

* This will also maximize application portability to older SAX
