Thanks Josselin, clear explanations as ever!
I tried those changes but initially didn't get anywhere. 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):
<xf:trigger>
<xf:label>New role</xf:label>
<xf:insert
nodeset="instance('template')/listPerson/person/occupation"
at="index('repeat-occ')"
position="after" ev:event="DOMActivate" />
</xf:trigger>
I'm a bit confused by this as the examples in the implementation file
have a mix of xf: and non-xf: and work fine, but my xml seems to need
every element marked 'xf:'.
Anyway, many thanks - and hopefully I'll leave you in peace for a while
now!

I've stripped back the model (and added a couple of other bits) and working round different Xpath permutations for the groups/elements has given me some confidence in that. But the triggers, while rendering fine, don't do anything.

This form is a partial success in that the form does render, and the s01 submission demonstrates that the src xml has been found and read. However, the input fields (and I've deliberately kept this short after the full model failed) do not appear (see image). There are no errors in the trace log and the profiler recognises that the 2 input fields exist. They just aren't being displayed.
