There is a mismatch in fold-right:

Signature:
   fn:fold-right( ., ., $f as function(item()*, item()) as item()*) as item()*

First parameter: item() sequence, second item()

Rules:
   else $f(fn:head($seq), fn:fold-right(fn:tail($seq), $zero, $f))

First parameter: item(), second item() sequence (the result type of $f)

Yes, that too.

So, to summarize, Wolfgang and I found three issues in the
specification of the fold -xxx functions:

      1. The Error Conditions paragraph for fold-left conflicts with
the signature of the function.

      2. The Error Conditions paragraph for fold-right conflicts with
the signature of the function.

      3. The Rules section (code) for fold-right conflicts the
signature of the function.
