 *
 * <p>This is an optional extension handler for SAX2. XML readers are not 
 * required to recognize this handler, and it is not part of core-only 
 * SAX2 distributions.</p>
 *
 * <p>This interface may be used with with a Fast Infoset
 * SAX parser to receive notification of data encoded using the
 * following built-in encoding algorithms specified in ITU-T Rec. X.891 | ISO/IEC 24824-1
 * (Fast Infoset), clause 10: "boolean", "base64", "short", "int", "long",
 * "float", "double" and "uuid" encoding algorithms.<p>
 *
 * <p>To set the PrimitiveTypeContentHandler for an XML reader, use the
 * {@link org.xml.sax.XMLReader#setProperty setProperty} method
 * with the property name
 * <code>URI TO BE DEFINED</code>
 * and an object implementing this interface (or null) as the value.
 * If the reader does not report primitive data types, it will throw a
 * {@link org.xml.sax.SAXNotRecognizedException SAXNotRecognizedException}</p>
 *
 * <p>To set the PrimitiveTypeContentHandler for an Fast Infoset reader, use
 * {@link org.jvnet.fastinfoset.sax.FastInfosetReader#setPrimitiveTypeContentHandler
 *  setPrimitiveTypeContentHandler} method.<p>

 * <p>The Parser will call methods of this interface to report each 
 * chunk of character data that has been converted to an array of primitive 
 * types, for example an array of integer or an array of float. Parsers may 
 * return all contiguous primtive types in a single chunk, or they may split 
 * it into several chunks</p>
 *
 * <p>The application must not attempt to read from the array
 * outside of the specified range.</p>
