RE: SWAP Example

You're absolutely right.  This is due to my silly error in changing the case
of the namespace prefix to capital "D:".  Also, I was wrong about closing
the </xml> tag.  And, I found a 3rd error:  namespaces are scoped to the
current element and contained elements, so the "z:" namespace in the example
has to be either redeclared for every z: element, or must be declared in
some element which contains all the z: elements.  This revised XML works:

<?xml version="1.0" ?> 
<d:swap xmlns:d="SWAP:"> 
  <d:observer>http://www.ics.uci.edu/pub/ietf/swap/chair.html</d:observer>
   <d:name>equipment-purchase-process</d:name> 
   <d:subject>procurement</d:subject> 
   <d:description>New equipment purchase</d:description> 
   <d:contextData> 
     <z:processor
xmlns:z="http://conf.pcmanufact.com/">pentiumII</z:processor> 
     <z:memory  xmlns:z="http://conf.pcmanufact.com/"> 
       <z:size>256 Meg</z:size> 
       <z:speed>60 ns</z:speed> 
       <z:type>DRAM</z:type> 
     </z:memory> 
   <!-- "name, billing address, etc." --> 
   </d:contextData> 
   <d:startImmediately>no</d:startImmediately><!-- "available?"-->
 </d:swap> 
 
It also works to declare the z: namespace on just the "swap" element, even
though that's not part of the z: namespace..

Just a note:
	When I run this example through IE 5.0 (which has XML support), I
get the following error:
Reference to undeclared namespace prefix: 'd'. Line 2, Position 25 
<d:swap xmlns:D="SWAP:">
