Hi Ralph,

For the xf: and non-xf: elements, it depends how and where you declare the xforms namespace. 
With your form you declared the namespace with the prefix xf: on the html tag : xmlns:xf="http://www.w3.org/2002/xforms", so, as you noticed, you need to use this xf prefix with the xforms elements.
 Best,
Josselin

Certainly the context was wrong in the first <repeat>, but it turns out that  - in my instance at least - I needed to mark the <insert> as <xf:insert> - it then worked just as expected, so (sorry, I didn't do the verbose although your explanation was extremely helpful):

But the triggers, while rendering fine, don't do anything.
