So the input for the form (from register-model.xpl) is:

What do you mean by the "input for the form"?
Now what I want to do is add a value to message in the asterisked section, i.e. something like:
<result when="/result/knownUID = 'true'"> <xu:update select="/input/message">Known UID</xu:update> </result>
As you are staying on the same page, the document you are updating with XUpdate is the current instance. It looks like the root element for your current instance is "result", so the "select" expression in <xu:update select="..."> should start with "/result", not "/input". If you tell XUpdate to do something on "/input/..." and the root element is "result", nothing will happen, which is what you observe.
