Package overview for net.sf.saxon.number
This package provides classes associated with numbering and the xsl:number element.
It is possible to extend the range of numberings available by providing a Numberer
for a specific language. This must be registered with the Configuration.
In earlier releases, there was a fixed relationship between the language and the
implementing class (the Numberer was always named Numberer_xx where xx is the language code,
corresponding to the value of the lang attribute in xsl:number). From Saxon 9.2,
this relationship no longer exists.
These classes also include code to support the localization of dates as defined
in the XSLT format-dateTime() group of functions.
The class Numberer_en provides the standard numbering options. As well as the
format tokens defined in the XSLT 1.0 specification (for example, "1", "001", "a", "i") it supports
other numbering options including:
Greek upper and lower case letters
Cyrillic upper and lower case letters
Hebrew letters
Japanese: Hiragana-A, Hiragana-B, Katakana-A, or Katakana-B letters, and Kanji digits
English words: the format token "one" produces numbers such as "twenty five"
Localizations for a number of European languages are provided in package net.sf.saxon.option.local.
In Saxon-PE and Saxon-EE these are issued in binary form as part of the Saxon JAR. For Saxon-HE, they are
issued only in source code form.
