------------------------------------------------------------------------------
  ''NOTE:'' Extension properties cannot be treated entirely generically. They 
can be accessed in a generic way and ''wrapped'' as generic 
{{{ExtensionProperty}}} objects, but the caller will still need to know what to 
do with the {{{java.lang.Object}}} returned by the 
{{{ExtensionProperty.getContent()}}} method - what to cast it to or whether it 
implements a useful toString() method. Woden should possibly provide some 
guidance here, like ''"extension implementors should define a suitable 
{{{toString()}}} method for their extension properties, or for items in an 
extension property based on a set."''. Then, client applications like GUI tools 
can at least display extension property content without needing to know what 
type of object it is. As the Woden API convention is to return typed-arrays for 
a ''set'' property, applications could just check for an Array type, then call 
{{{toString()}}} on each element.
  
  === API change impact ===
- Changes to the {{{WSDLComponent}}} API are:
-  * {{{ComponentExtensions getComponentExtensionsForNamespace(NSuri)}}} is 
replaced by {{{ComponentExtensionContext getComponentExtensionContext(NSuri)}}}
-  * 
+ Most of the API changes in WODEN-47 are additions to the API. Changes to the 
existing API have been minimized to keep the new extension model largely 
backward-compatible.
+ 
+ The necessary changes to the existing API are:
+  * calls to {{{WSDLComponent.getComponentExtensionsForNamespace(NSuri)}}} 
must be replaced with {{{WSDLComponent.getComponentExtensionContext(NSuri)}}} 
(the extension subtypes like {{{SOAPBindingExtensions}}} have been changed to 
the new super-type, so those APIs will not be affected)
+  * calls to {{{ExtensionRegistry.createComponentExtension}}} will now return 
{{{ComponentExtensionContext}}} instead of {{{ComponentExtensions}}}, but this 
method is typically called by Woden anyway, not by user code.
