arch:extract-map multiple methods

[whyme]

I am experimenting with the expath-archive function library. So far, arch:*-map() functions in general seem to work fine, but whenever I invoke arch:extract-map($i, $j), I get this validation error:
[Saxon-EE 9.8.0.12] There is more than one method matching the function call arch:extract-map, and there is insufficient type information to determine which one should be used

This happens even when I have explicitly assigned types to input $i and $j. oXygen doesn't give function prompts for the expath-archive function library, so I can't tell what's expected of me. Does Saxon EE have multiple 2-arity forms of arch:extract-map()? Any suggestions?

Hi,

We are not familiar with expath, maybe you can ask around on the Saxon users list.
