To specify the number of digits in a number
<source lang="xml">
You can limit the number of digits to the right or left of the decimal point of a number. xsd:precision facet must be a positive number (1, 2, 3, or higher). xsd:precision may not be equal to zero. xsd:precision may not be less than the xsd:scale value. xsd:scale facet must be a non-negative integer (0, 1, 2, or higher). Both the xsd:precision and xsd:scale facets specify the maximum values allowed. The number is still considered valid if fewer digits are present. You may set a xsd:precision and xsd:scale for any numerical type, but not for any string, date, or other types.
