public class ObjectValue
An XPath value that encapsulates a Java object. Such a value can only be obtained by calling an extension function that returns it.

public 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.

ordered
- true if an ordered comparison is required. In this case the result is null if the
type is unordered; in other cases the returned value will be a Comparable.collator
