Formatting currencies

[Rafael Xavier]

One more question.

3.2 Special Pattern Characters
<http://www.unicode.org/reports/tr35/tr35-numbers.html#Special_Pattern_Characters>

¤ (U+00A4) Prefix or suffix No Currency sign, replaced by currency symbol. If
doubled, replaced by international currency symbol. If tripled, uses the
long form of the decimal symbol. If present in a pattern, the monetary
decimal separator and grouping separators (if available) are used instead
of the numeric ones.

The doubled and tripled forms are simply not mentioned in 4 Currencies
<http://www.unicode.org/reports/tr35/tr35-numbers.html#Currencies> section.
There's also no mention defining what the "long form" is. Instead, there is
displayName and there's an extensive algorithm explaining how displayNames
should be implemented. It's also important to notice that unitPattern
potentially varies depending of the plural count form. The tripled form
doesn't support such variation. Therefore, they are not equivalent.

Are the doubled and tripled forms defined somewhere else? Have they been
deprecated and the above table not updated?
