yes but setting a variable isn't configuring anything and you can always
replace a variable reference by its value, so if you only use it in one
place it's not doing anything except perhaps make the stylesheet look a
bit more self-documenting (which isn't a negligible consideration)

well as I said before you can't use element()+ as the type of a sequence
selected by doc() as you'll get a type error.
Either doc() will return the empty sequence, in which case you get an
error (as you have used + which means 1-or-more) or it will return a
document node, in which cae you will get an error as you have used
element() (which means an element node)
