This version of CharacterMapping.dtd is modified by
Markus Scherer on 2001-08-09 to include the proposed additions
from L2/01-180:
1. add XML mapping table support for "subchar1" as used in IBM converters
2. add XML mapping table support for simple stateful (SI/SO) encodings
3. add XML mapping table support for ISO 2022 country variants
The additions are marked with comments MS1..MS3.
