two true statements

a statement that's not quite as true as one might wish...

I don't want to index with . (the value on the sequence) but with
current() the index value coming from the for-each, if I use current()
my statement that you only get one item is true and the code  works (I
claim)

even ran it past saxon this time:-0

sorry about that.
