* SAX2 distributions.

* This interface may be used with with a Fast Infoset
* 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
* application defined encoding algorithms specified as part of the
* initial vocabulary of a fast infoset document.
*
*
To set the EncodingAlgorithmContentHandler for an XML reader, use the
* {@link org.xml.sax.XMLReader#setProperty setProperty} method
* with the property name
* URI TO BE DEFINED
* 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
* setEncodingAlgorithmContentHandler} method.
