This also allows consumers to push a SAX interner (a filter) onto the
producer, so that all output from the filter is interned.  This needs
to be done just once, at setup time, so no other part of the consumer
is affected.  And there's no overhead added if the producer generates
interned names.


    boolean namesAreInterned =
        xmlReader.getFeature("http://xml.org/sax/features/interned-names");

    if (namesAreInterned)
        xmlReader = new SAXInterner(xmlReader);

    // The 'interned-names' feature will always be true at this point.

    // Now add the handlers...
