20    * <p>An XML filter is like an XML reader, except that it obtains its
21    * events from another XML reader rather than a primary source like
22    * an XML document or database. Filters can modify a stream of
23    * events as they pass on to the final application.</p>
24    *
25    * <p>The XMLFilterImpl helper class provides a convenient base
26    * for creating SAX2 filters, by passing on all {@link org.xml.sax.EntityResolver
27    * EntityResolver}, {@link org.xml.sax.DTDHandler DTDHandler},
28    * {@link org.xml.sax.ContentHandler ContentHandler} and {@link org.xml.sax.ErrorHandler
29    * ErrorHandler} events automatically.</p>
