</xs:restriction>
</xs:simpleType>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.".
