Hello Amanda,

you are invited to delete that. I am pretty sure that is left from a change to the spec (and accordingly the change in our function signatures). Some time ago, the argument order for the HOF functions in the spec was changed, moving the sequence items to the first argument position. So the gray version is actually outdated and as we didn't keep in the the other function signatures I think it is safe to delete it.

Cheers, Dirk

Hi,

The documentation page http://docs.basex.org/wiki/Higher-Order_Functions#fn:filter shows two signatures for the fn:filter function, the second of which is in gray. Does it belong? It doesn't seem to work or match the spec, but I'm hesitant to delete it from the wiki in case I am wrong.

fn:filter($seq as item()*, $pred as function(item()) as xs:boolean)) as item()* fn:filter($pred as function(item()) as xs:boolean, $seq as item()*) as item()*

Thanks, Amanda
