<P>
Saxon implementation of the JAXP class javax.xml.datatype.Duration. This is currently used only by the XQJ
interface for XQuery: the normal representation of a duration in Saxon is the class <A HREF="../../../../net/sf/saxon/value/DurationValue.html" title="class in net.sf.saxon.value"><CODE>DurationValue</CODE></A>.
<p>
The JAXP specification for this class defines it in terms of XML Schema 1.0 semantics. This defines a structure
with six independent components (year, month, day, hour, minute, second). This implementation is more aligned
to the XPath 2.0 semantics of the data type, which essentially defines duration as an integer number of months plus
a decimal number of seconds.

<DL>
<DD>Gets the value of a field.
<p/>
Fields of a duration object may contain arbitrary large value.
Therefore this method is designed to return a <A HREF="http://download.oracle.com/javase/6/docs/api/java/lang/Number.html?is-external=true" title="class or interface in java.lang"><CODE>Number</CODE></A> object.
<p/>
In case of YEARS, MONTHS, DAYS, HOURS, and MINUTES, the returned
number will be a non-negative integer. In case of seconds,
the returned number may be a non-negative decimal value.
<p/>
The Saxon implementation of duration uses normalized values. This means
that the YEARS and DAYS fields may be arbitrarily large, but other
components will be limited in size: for example MINUTES will never
exceed 60 and MONTHS will never exceed 12.

order of YEARS, MONTHS, DAYS, HOURS, MINUTES, SECONDS, and MILLISECONDS

uses int to hold values, there are cases where this method
won't work correctly (for example if values of fields
exceed the range of int.)
</p>
<p/>
<p/>
Also, since this duration class is a Gregorian duration, this
method will not work correctly if the given <A HREF="http://download.oracle.com/javase/6/docs/api/java/util/Calendar.html?is-external=true" title="class or interface in java.util"><CODE>Calendar</CODE></A>
object is based on some other calendar systems.

<p/>
Any fractional parts of this <code>Duration</code> object
beyond milliseconds will be simply ignored. For example, if
this duration is "P1.23456S", then 1 is added to SECONDS,
234 is added to MILLISECONDS, and the rest will be unused.

<p/>
Note that because <A HREF="http://download.oracle.com/javase/6/docs/api/java/util/Calendar.html?is-external=true#add(int, int)" title="class or interface in java.util"><CODE>Calendar.add(int, int)</CODE></A> is using
