So here is an interesting question.

Lets say I have a nodeset variable (PAYLOAD) that I am for-each looping

Then I strip by XPATH a node out of it, the clone by XPATH a node back
into it.

What happens to my loop? Does it loop on the version it started with,
or does it loop on the current state of the nodeset, each time it hits
the beginning of the loop?

Sort of like adding and removing steps, while walking up the stair

I will try and experimentally determine this, but be nice if someone
already tried this foolish approach and knows the answer.
