Please standardize "Line Start Prohibition Rule"

Dear colleagues,

Open Office appear to support "line-start prohibition rule", and even
allows document authors to specify which character is prohibited.
This rule is considered very important in Japan, China, Taiwan, and
Korea.

http://www.w3.org/TR/2009/NOTE-jlreq-20090604/#en-subheading2_1_7

If you explicitly specify which character is prohibited, the following
is generated by OO.o as part of setting.xml.

      <config:config-item-map-indexed config:name="ForbiddenCharacters">
        <config:config-item-map-entry>
          <config:config-item config:name="Language" config:type="string">ja</config:config-item>
          <config:config-item config:name="Country" config:type="string">JP</config:config-item>
          <config:config-item config:name="Variant" config:type="string"/>
          <config:config-item config:name="BeginLine" config:type="string"
            >!%),.:;?]}¢°’”‰′″℃、。々〉》」』】〕ぁぃぅぇぉっゃゅょゎ゛゜ゝゞァィゥェォッャュョヮヵヶ・ーヽヾ！％），．：；？］｝｡｣､･ｧｨｩｪｫｬｭｮｯｰﾞﾟ¢</config:config-item>

            >$([¥{£¥‘“〈《「『【〔＄（［｛｢£￥</config:config-item>
        </config:config-item-map-entry>

However, their semantics is not at all described in ODF 1.0.  It is not 
described in the current draft of ODF 1.2 either.  Please standardize
them.  Otherwise, ODF 1.2 does not contribute to interoperability 
of Japanese text.


Cheers,
Makoto
