1. The standard does not clearly define TypeA and TypeC for the ea1ChsPlain and the ea1ChtPlain values of the ST_TextAutonumberScheme simple type.

In Office, TypeA: The Chinese character “十” is used to represent 10. For example, 20 is represented as 二十 and 99 is represented as 九十九.

TypeC: each digit is written out separately and zero is represented by the ideographic Chinese character "〇". For example, 20 is represented as 二〇, 99 is represented as 九九 and 102 is represented as 一〇二.
