/**
* xsltFormatNumberConversion:
* @self: the decimal format
* @format: the format requested
* @number: the value to format
* @result: the place to ouput the result
*
* format-number() uses the JDK 1.1 DecimalFormat class:
*
* http://java.sun.com/products/jdk/1.1/docs/api/java.text.DecimalFormat.html
*
* Structure:
*
* pattern := subpattern{;subpattern}
* subpattern := {prefix}integer{.fraction}{suffix}
* prefix := '\\u0000'..'\\uFFFD' - specialCharacters
* suffix := '\\u0000'..'\\uFFFD' - specialCharacters
* integer := '#'* '0'* '0'
* fraction := '0'* '#'*
*
* Notation:
* X* 0 or more instances of X
* (X | Y) either X or Y.
* X..Y any character from X up to Y, inclusive.
* S - T characters in S, except those in T
*
* Special Characters:
*
* Symbol Meaning
* 0 a digit
* # a digit, zero shows as absent
* . placeholder for decimal separator
* , placeholder for grouping separator.
* ; separates formats.
* - default negative prefix.
* % multiply by 100 and show as percentage
* ? multiply by 1000 and show as per mille
* X any other characters can be used in the prefix or suffix
* ' used to quote special characters in a prefix or suffix.
*
* Returns a possible XPath error
