Add an element and delete it's child

Hello,

I am trying to create a form where, if a given element is missing from
my instance, I add it. The only thing is, in my template instance, the
element I'm adding has a child element. (which is used as the template
for adding more of that child.)

I tried to create an action that will add the element I'm looking for,
and then immediately remove it's child. It's not doing it. Is there a
way to delete a sub-element from an element that has just been added,
or better yet, to add that element but not it's child?

I suppose as a workaround, I could have two templates (one with and
one without) but I'd that seems like a waste as I'd either have to
have two instances, or have my instance be invalid as per my schema.

I've attached a minimal testcase that shows what I'm doing.

Attached is the corrected testcase. (I also added the instance inspector)

This is a tricky case: when you do the first insert, since the group
in which all of this is running has ref=".[not(myc:chat)], after the
insert, there is no more context, so the delete doesn't do anything
because there is no context to run it into.

I changed the ref="..." expression on the group to avoid this problem,
but still have the same behavior. Also I fixed the syntax of the
delete to use just nodeset="...". Your updated example is attached.
