  The method javax.xml.datatype.Duration.toString() returns illegal string representations for
very short durations. For example:
new Duration("PT0.00000000000000001S").toString() returns "PT1E-17S".

The documentation of the method 'toString()' reads:
"Returns a string representation of this duration object. The result is formatter according to
the XML Schema 1.0 spec and can be always parsed back later into the equivalent duration object
by the Duration(String) constructor." In our case, the value "PT1E-17S" cannot be parsed back,
so the method 'toString' has a bug.

This bug affects new test in JCK 1.5 (not yet integrated)
   api/javax_xml/datatype/Duration/index.html#DurationTests[Ctor010]

To reproduce the bug compile and run the following code as shown
in the log below:
------------------------------ test.java
import javax.xml.datatype.Duration;

public class test {
    public static void main(String [] args) {
        System.out.println(
             "new Duration(\"PT0.00000000000000001S\").toString() returns "
            + new Duration("PT0.00000000000000001S").toString());
    }
}
