Description

The value space of xs:integer includes the set of all the signed integers, with no restriction on range. Its lexical space allows any number of insignificant leading zeros.

Restrictions

The decimal point (even when followed only by insignificant zeros) is forbidden.

-0 and +0 are considered equal, which is different from the behavior of xs:float and xs:double.

Example

Valid values for xs:integer include "-123456789012345678901234567890", "2147483647", "0", or "-0000000000000000000005".

Invalid values include "1.", "2.6", and "A".
