Discussion
Alex: could we have the context, please, which is what it says underneath. I've looked for it online but, unlike that in your previous question, haven't found it.
It looks like the other question is boilerplate text, but this isn't.
Probably, the whole phrase ("dichiarazione...") just means "undertaking".
