Can't figure out formxml in customisations.xml

Hi,

I wrote a small tool that lists all the fields on a form, been running good up until now.

I construct the solution on the fly, then export it and parse the form xml's.

However lately I have some occurences where the fields (normal/header/footer) do not have a control tag.

The control tag should tell which field this is. How does D365 know what field to display then?

This is what is shown in the designer :

This is what is exported in the solution

Any thoughts?
