The type xsd:decimal represents a decimal number of arbitrary precision. Schema processors vary in the number of significant digits they support, but a conforming processor must support a minimum of 18 significant digits. The format of xsd:decimal is a sequence of digits optionally preceded by a sign ("+" or "-") and optionally containing a period. The value may start or end with a period. If the fractional part is 0 then the period and trailing zeros may be omitted. Leading and trailing zeros are permitted, but they are not considered significant. That is, the decimal values 3.0 and 3.0000 are considered equal.
