各种内置类型详解
1：string及其相关类型
string：保留原始字符串。
normalizedString：字符串中Newline、tab和carriage-return都会被替换成空白。
token：字符串中Newline、tab和carriage-return都会被替换成空白，并且字符串中间连续的空白会被压缩成一个，字符串前后的空白会被自动删除。
Name：要求是合法的XML签名。
NCName：不带命名空间的XML签名。
QName：带命名空间的XML签名。
由string派生出来的ID、IDREF、ENTITY、ENTITIES、NMTOKEN、NMTOKENS类型只能用来约束属性。
ID：标识符。
IDREF：引用另一个ID。
IDREFS：引用多个已有的ID，空格为分隔符。
NMTOKEN：必须是合法的XML名称，只能由字母、数字、_、-、.、:组成。
NMTOKENS：多个NMTOKEN，空格为分隔符。
ENTITY：外部实体。
ENTITIES：多个外部实体，空格为分隔符。
