Okay, using my latest build, I get the following trace when I send a message payload that
doesn't use prefixes:

This is very weird. The NotificationMessage element is removed! the <wsnt:NotificationMessage
part is erased, but the namespace declarations remain as text, and the closing bracket (>)
has been normalized to the proper character code (as if it were text data). When you put a
prefix back in, the NotificationMessage element remains.

Because the NotificationMessage element is removed (and its children become Notify's children),
the parser gets screwed up.

I honestly don't know what to do about this, because that server-side logging (LoggingUtils.logMessage())
happens right after the XML is received from Axis2. I'm guessing it may be an Axis2 problem,
but I will doublecheck using our new "mini" platform tonight.

> Sending a notification containing a complex element doesn't seem to work.  It only works
for an element containing a simple string message.  I'm using XmlBeans for conversion between
xml schemas and java objects.  Using the code below, the notification does not appear to be
sent, nor do any errors get thrown in the process.
> BoxDocument doc = BoxDocument.Factory.newInstance();
> BoxType type = doc.addNewBox();
> type.setWidth(BigInteger.valueOf(123));
> type.setHeight(BigInteger.valueOf(123));
> QName qname = new QName(NAMESPACE_URI, "MyMessage", PREFIX);
> Element payload = XmlUtils.createElement(qname, XmlUtils.getFirstElement((Document)doc.getDomNode()));
> NotificationProducer np = ...
> np.publish(TOPIC_NAME, payload);
> Here is the XML from doc.xmlText():
> <box:Box xmlns:box="http://cisco.com/musebox/schemas/box"><box:width>123</box:width><box:height>123</box:height></box:Box>
