在XSD中表示2D字符

我是XSD的新手。我有一个需要在XSD中表示的结构：

struct  
{
  int num;
  char token[10]
  char value[20][10];
} test;

我如何在XSD中提到“值”？我可以将其他元素表示为：

<complexType name=test>
  <sequence>
    <element name='num' type='int'/>
    <element name='token' type='string' minOccurs='0' maxOccurs='unbounded'/>
  </sequence>
</complexType>

此XSD将用于生成C++代码

谢谢
