* SAX parser to receive notification of encoding algorithm data specified
* in ITU-T Rec. X.891 | ISO/IEC 24824-1 (Fast Infoset) clause 10 and for

* {@link org.xml.sax.XMLReader#setProperty setProperty} method
* with the property name

* 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}

* To set the EncodingAlgorithmContentHandler for an Fast Infoset reader, use
* {@link org.jvnet.fastinfoset.sax.FastInfosetReader#setEncodingAlgorithmContentHandler
