/**
* <P> Pattern formats are used to put together sequences of strings, numbers,
* dates, and other formats to create messages. The pattern formatters
* facilitate localization because they prevent both hard-coding of message
* strings, <I> and </I> hard-coding of the concatenation sequence for portions
* of message strings. This means localizers can change the content, format,
* and order of any text as appropriate for any language.

* <P> The pattern is a sequence of text and arguments, all of which can be
* edited. The positions of the arguments within the sequence are indicated
* by a "%" followed by a digit <I> n </I> identifying the
* argument. The pattern in the demo applet has three arguments, numbered 0,
* 1, and 2. The arguments can appear in any order within the sequence, which
* can be edited and modified.

* works even in more complicated contexts, such as Slavic languages which
* have more than one plural format based on the number involved. A particular
* choice is chosen based on the value of the argument, and each choice can be
* edited individually.
* </P>
* <P> Look also at the format for the choice associated with values of 2 and
* higher, "%0|3". The vertical bar indicates that the choice
* uses the value for argument 0, but the format for argument 3 (in this case,
* a Number). This allows for a degree of flexibility in using different
* formats.
