* MIME2Java is a convenience class which handles conversions between MIME charset names

* <p>The supported XML encodings are the intersection of XML-supported code sets and those
* supported in JDK 1.1.
* <p>MIME charset names are used on <var>xmlEncoding</var> parameters to methods such
* as <code>TXDocument#setEncoding</code> and <code>DTD#setEncoding</code>.
* <p>Java encoding names are used on <var>encoding</var> parameters to
* methods such as <code>TXDocument#printWithFormat</code> and <code>DTD#printExternal</code>.
