Dear Saxon,
=20
When working with fold-left and fold-right, I noticed that the signature =
of the supplied function is not the same.
=20
Currently the documentation on saxonica.com of fold-left shows the same =
signature as fold-right. =
https://www.saxonica.com/documentation10/index.html#!functions/fn/fold-le=
ft
=20
It shows the accumulator as last:
=20
function(item(), item()*)
=20
But the accumulator should be the first parameter:
=20
function(item()*, item())
=20
Link to the spec: =
https://www.w3.org/TR/xpath-functions-31/#func-fold-left
=20
Regards,
Frank
