requiredType
- the required atomic type. This must either be a primitive type, or a built-in
type derived from the same primitive type as this atomic value.validate
- true if validation is required. If set to false, the caller guarantees that
the value is valid for the target data type, and that further validation
is therefore not required.
Note that a validation failure may be reported even if validation was not requested.public java.lang.CharSequence getPrimitiveStringValue()

public java.lang.Comparable getSchemaComparable()
AtomicValue
In the case of data types that are partially ordered, the returned Comparable extends the standard
semantics of the compareTo() method by returning the value Value.INDETERMINATE_ORDERING
when there
is no defined order relationship between two given values. This value is also returned when two values
of different types are compared.

- true if an ordered comparison is required. In this case the result is null if the
