If I create a form with embedded html mail template, this form can no longer be
saved and imported via the xml format.
Well the form can be saved without problems, but if you try to import the form
the xml parser rejects the file.
I assume the embedded html form is not excaped in a way that would ensure xml
compatibility in all cases.
(E.G. I use html comments in the form)
