I try to use x_i as independent variables
a = Table[Subscript[x, i], {i, 1, 2}]
{Subscript[x, 1], Subscript[x, 2]}

Now if I do.
Dt[a]

I get smth that I dont understand at all

List[Times[Dt[x],Derivative[1,0][Subscript][x,1]],Times[Dt[x],Derivative[1,0][Subscript][x,2]]]

It seems that its think that Subscript is also variable....I dont wantit!
