Construct an unsignedLong
value from an item
value.
The following construct(s) refer to this construct:
xs:unsignedLong(item $value) => unsignedLong
This is a constructor function that takes an item value as argument and
returns a value of type xs:unsignedLong
. If the argument is a
literal, then the literal must be a valid lexical form of its type.
As specified in the respective section of the W3C recommendation
XML Schema Part 2: Datatypes, a value of type
xs:unsignedLong
represents an integer value derived from
xs:nonNegativeInteger
. The lexical representation is the set of
unsigned numerical values in the range from 0 to 18446744073709551615.

The following queries construct valid values of type
xs:unsignedLong
:
xs:unsignedLong(18446744073709551615)
xs:unsignedLong(-0)
The following queries do not construct valid values of type
xs:unsignedInt
:
xs:unsignedLong(18446744073709551616)
xs:unsignedLong(-223)
