<DL>
<DD>Constructs a <code>CompositeType</code> instance, checking for the validity of the given parameters.
 The validity constraints are described below for each parameter. 
 <p>
 Note that the contents of the three array parameters 
 <var>itemNames</var>, <var>itemDescriptions</var> and <var>itemTypes</var>
 are internally copied so that any subsequent modification of these arrays by the caller of this constructor
 has no impact on the constructed <code>CompositeType</code> instance.
 <p>
 The Java class name of composite data values this composite type represents 
 (ie the class name returned by the <A HREF="../../../javax/management/openmbean/OpenType.html#getClassName()"><CODE>getClassName</CODE></A> method) 
 is set to the string value returned by <code>CompositeData.class.getName()</code>.
 <p>
<P>
<DT><B>Parameters:</B><DD><CODE>typeName</CODE> - The name given to the composite type this instance represents; cannot be a null or empty string.
 <br>&nbsp;<DD><CODE>description</CODE> - The human readable description of the composite type this instance represents; 
			    cannot be a null or empty string.
 <br>&nbsp;<DD><CODE>itemNames</CODE> - The names of the items contained in the 
			  composite data values described by this <code>CompositeType</code> instance; 
			  cannot be null and should contain at least one element; no element can be a null or empty string.
                    Note that the order in which the item names are given is not important to differentiate a
			  <code>CompositeType</code> instance from another;
			  the item names are internally stored sorted in ascending alphanumeric order.
 <br>&nbsp;<DD><CODE>itemDescriptions</CODE> - The descriptions, in the same order as <var>itemNames</var>, of the items contained in the 
			         composite data values described by this <code>CompositeType</code> instance; 
				 should be of the same size as <var>itemNames</var>;
				 no element can be a null or empty string.
 <br>&nbsp;<DD><CODE>itemTypes</CODE> - The open type instances, in the same order as <var>itemNames</var>, describing the items contained  
			  in the composite data values described by this <code>CompositeType</code> instance; 
			  should be of the same size as <var>itemNames</var>;
			  no element can be null.
