/**
* 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.
