XML base types

The list of valid XML base types for the base attribute of xs:restriction, the associated regex expression to check for the validity of string representation, and the allowed nodes inside the xs:restriction are as follows:

Base type Value string regex constraint annotation pattern enumeration minLength maxLength length minExclusive maxExclusive minInclusive maxInclusive
xs:boolean ^(true|false|0|1)$ ✓ ✓
xs:date ^\d{4}-\d{2}-\d{2}(Z|([+-]\d{2}:\d{2}))?$ ✓ ✓ ✓ ✓ ✓ ✓ ✓
xs:dateTime ^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}(.\d+)?(Z|([+-]\d{2}:\d{2}))?$ ✓ ✓ ✓ ✓ ✓ ✓ ✓
xs:double ^([-+]?[0-9].?[0-9]([eE][-+]?[0-9]+)?|NaN|+INF|-INF)$ ✓ ✓ ✓ ✓ ✓ ✓ ✓
xs:duration ^[-+]?P(\d+Y)?(\d+M)?(\d+D)?(T(\d+H)?(\d+M)?(\d+S)?)?$ ✓ ✓ ✓ ✓ ✓ ✓ ✓
xs:integer ^[+-]?(\d+)$ ✓ ✓ ✓ ✓ ✓ ✓ ✓
xs:string ^.*$ ✓ ✓ ✓ ✓ ✓ ✓
xs:time ^\d{2}:\d{2}:\d{2}(.\d+)?(Z|([+-]\d{2}:\d{2}))?$ ✓ ✓ ✓ ✓ ✓ ✓ ✓

For example:

  • To specify numbers: you must use a dot as the decimal separator, and not use a thousands separator (e.g. 4.2 is valid, but 1.234,5 is invalid). Scientific notation is allowed (e.g. 1e3 to represent 1000).
  • To specify a boolean: valid values are true or false, 0, or 1.
