Name

xs:totalDigits — Facet to define the total number of digits of a numeric datatype.

Synopsis

<xs:totalDigits
           fixed          = xs:boolean : “false”
           id             = xs:ID
           value          = xs:positiveInteger
           {any attributes with non-schema namespace}
           >
           Content: (xs:annotation?)
</xs:totalDigits>

May be included in: xs:restriction (simple type), xs:restriction (simple content)

May be used as facet for: xs:byte, xs:decimal, xs:int, xs:integer, xs:long, xs:negativeInteger, xs:nonNegativeInteger, xs:nonPositiveInteger, xs:positiveInteger, xs:short, xs:unsignedByte, xs:unsignedInt, xs:unsignedLong, xs:unsignedShort

Description

xs:totalDigits defines the maximum number of digits of decimal and derived datatypes (both after and before the decimal point, not counting the decimal point itself).

This facet constrains the value space, which means that the number of digits is checked after the value is transformed to its canonical form and the leading and trailing zeros are removed.

Restrictions

It is also possible to use xs:pattern to constrain the number of total digits in the lexical space.

Within a restriction step, xs:totalDigits is dependent on xs:fractionDigits since using inconsistent values leads to datatypes with empty value spaces.

xs:totalDigits must restrict the value space of its base type. Its value must be smaller than the value of the xs:totalDigits of its base type if defined.

Example

<xs:simpleType name="totalDigits"> <xs:restriction base="xs:integer"> <xs:totalDigits value="5"/> </xs:restriction> </xs:simpleType> ...
