I agree to that. I stuck with the [1] in my code.

I would recommend using the "[1]", because then your code won't throw an
error when the stylesheet is upgraded to version="2.0". Also, I think
it's
good generally not to rely on the implicit discarding of items in a
sequence
after the first, simply because it makes your code clearer to make it
explicit.
