Please don't start a flamewar about almost nothing.

Alberto, I thank you for the clarification.
I was irritated by the term 'shroud', first, because I didn't find a good translation for the word as the adjectiv as you used it, and second because the interpretation that I got from my dictionary sound too strong IMO.
Nonetheless, you spread light on this. Thanks.
