/**
* Enumeration of the style of text formatting and parsing.
*
* Text styles define three sizes for the formatted text - 'full', 'short' and 'narrow'.
* Each of these three sizes is available in both 'standard' and 'stand-alone' variations.
*
* The difference between the three sizes is obvious in most languages.
* For example, in English the 'full' month is 'January', the 'short' month is 'Jan'
* and the 'narrow' month is 'J'. Note that the narrow size is often not unique.
* For example, 'January', 'June' and 'July' all have the 'narrow' text 'J'.
*
* The difference between the 'standard' and 'stand-alone' forms is trickier to describe
* as there is no difference in English. However, in other languages there is a difference
* in the word used when the text is used alone, as opposed to in a complete date.
* For example, the word used for a month when used alone in a date picker is different
* to the word used for month in association with a day and year in a date.
*
*
Specification for implementors
* This is immutable and thread-safe enum.
