/**
 * MIME2Java is a convenience class which handles conversions between MIME charset names
 * and Java encoding names.
 * 

The supported XML encodings are the intersection of XML-supported code sets and those * supported in JDK 1.1. *

MIME charset names are used on xmlEncoding parameters to methods such * as TXDocument#setEncoding and DTD#setEncoding. *

Java encoding names are used on encoding parameters to * methods such as TXDocument#printWithFormat and DTD#printExternal. *
