I have a sequence of xs:string : ('amount', 'vat-rate', 'total')
And I want a map where keys are the labels from the sequence, and
values are the position of label in sequence : { 'amount': 1,
'vat-rate': 2, 'total': 3}

One way would be

(('amount', 'vat-rate', 'total') ! map:entry(., position())) =>
map:merge()
