推荐答案

区别如下:xs:int 是一个有符号的 32 位整数.xs:integer 是一个无界整数值.详情请参见 https://web.archive.org/web/20151117073716/http://www.w3schools.com/schema/schema_dtypes_numeric.asp例如，XJC (Java) 为 xs:int 生成 Integer，为 xs:integer 生成 BigInteger.

The difference is the following: xs:int is a signed 32-bit integer. xs:integer is an integer unbounded value. See for details https://web.archive.org/web/20151117073716/http://www.w3schools.com/schema/schema_dtypes_numeric.asp For example, XJC (Java) generates Integer for xs:int and BigInteger for xs:integer.

底线:如果您想跨平台工作并确保您的号码顺利通过，请使用 xs:int.如果你想要更大的数字 - 使用 xs:long 而不是 xs:integer(它会被生成为 Long).

The bottom line: use xs:int if you want to work cross platforms and be sure that your numbers will pass without a problem. If you want bigger numbers – use xs:long instead of xs:integer (it will be generated to Long).
