In Japanese typography, numbers are written in Arabic digit
for horizontal text (
or in Han (CJK ideographic) digit (such as
CJK UNIFIED IDEOGRAPH-4E00)
for vertical text (
Styling language that support both horizontal and
vertical layout should provide a way to display
representation of number in some other format
than in source document tree (as in
list-style-type for list bullets).
In addition, to support this styling (and, e.g. scripting) in semantic and standadized way, an element type whose instance contains a textual representation of a number should be introduced.
<p>そこには<number>100</number>個の林檎があります。</p> <!-- There were 100 apples. -->
This example markup should be rendered as...
そこには 100 個の林檎があります。
... or ...
そ こ に は 百 個 の 林 檎 が あ り ま す ゜
