/**
* To format numbers in locale sensitive manner use
*
*
*
*
* Numbers can be formatted as currency, percentage, decimal or scientific
* numbers by specifying the Type attribute. The known types are
* "currency", "percentage", "decimal" and "scientific".
*
* If someone from US want to see sales figures from a store in
* Germany (say using the EURO currency), formatted using the german
* currency, you would need to use the attribute Culture="de_DE" to get
* the currency right, e.g. 100,00. The decimal and grouping separator is
* then also from the de_DE locale. This may lead to some confusion because
* people from US know the "," as thousand separator. Therefore a "Currency"
* attribute is available, so that the output from the following example
* results in 100.00.
*
*
*
*
* Namespace: System.I18N
*
* Properties
* - Value, number,
*
Gets or sets the number to format. The tag content is used as Value
* if the Value property is not specified.
* - Type, string,
*
Gets or sets the formatting type. The valid types are
* 'decimal', 'currency', 'percentage' and 'scientific'.
* - Currency, string,
*
Gets or sets the currency symbol for the currency format.
* The default is 'USD' if the Currency property is not specified.
* - Pattern, string,
*
Gets or sets the custom number formatting pattern.
* - DefaultText, string,
*
Gets or sets the default text. If Value is not set, DefaultText will be
* shown instead of the default currency Value/Pattern.
