Description

The value space of xs:unsignedByte is the integers between 0 and 255, i.e., the unsigned values that can fit in a word of 8 bits. Its lexical space allows an optional “+” sign and leading zeros before the significant digits.

Restrictions

The lexical space does not allow values expressed in other numeration bases (such as hexadecimal, octal, or binary).

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

Example

Valid values include "255", "0", "+0000000000000000000005", or "1".

Invalid values include "-1" and "1.".
