But position() would return a number and it seems such an obvious way to use it as an index... Which number? 1 returns a number as well, and [1] means [position()=1] given that any numeric expression is turned into a filter by testing against position(). You wanted to access the value of position() current before the xpath started but for that you have to do index-of($sequence,position()) as a function such as index-of (unlike a path step or filter0 does not locally redefine position(). $sequence[5] and index-of($sequence,5) are the same thing but $sequence[position()] and index-of($sequence,position()) are different as in the first position() refers to position in the sequence so the filter is position()=position() and always true in the second position() refers to a value set in an outer context.
