  Method javax.xml.datatype.Duration.isLongerThan(Duration rhs) incorrectly
returns 'true' for the following arguments (this and rhs):
'P1M' and P28D',
'P1M' and P29D',
'P5M' and P150D'

The XML Schema Part 2: Datatypes, table in the Section 3.2.6.2
Order relation on duration reads:

"The following table shows the strongest relationship that can be
determined between example durations. The symbol <> means that the
order relation is indeterminate. ...

--------------------------------------------------------
  Relation
--------------------------------------------------------
P1Y | >P364D <>P365D <>P366D <P367D
P1M | >P27D <>P28D <>P29D <>P30D <>P31D <P32D
P5M | >P149D <>P150D <>P151D <>P152D <>P153D <P154D
--------------------------------------------------------
"

So the method javax.xml.datatype.Duration.isLongerThan(Duration rhs)
is expected to return false in the mentioned cases.

This bug affects new test in JCK 1.5 (not yet integrated)
   api/javax_xml/datatype/Duration/index.html#DurationTests[IsLongerThan001]

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

public class IsLongerThanTest {
    public static void main(String [] args) {
        System.out.println("P1M.isLongerThan(P28D) returns "
            + new Duration("P1M").isLongerThan(new Duration("P28D")));
        System.out.println("P1M.isLongerThan(P29D) returns "
            + new Duration("P1M").isLongerThan(new Duration("P29D")));
        System.out.println("P5M.isLongerThan(P150D) returns "
            + new Duration("P5M").isLongerThan(new Duration("P150D")));
    }
}
----------------------------------------------------

$java -cp . -showversion IsLongerThanTest
