Ben,

Apologies - I think I misread your email (and let some things I was thinking of steer the linking!).

For an XQuery module; e.g.

utilities.xqm
```

xquery version "3.1";
module namespace utils = "http://canofbees.org/ns/xquery/utilities";
 
declare function utils:atty(
  $att as attribute()
) as xs:string* {
  "[@" || name($att) || "='" || data($att) || "']"
};
 
declare function utils:pathing(
  $result as xs:string,
  $node as node()
) {
  concat(
    $result, "/"[$result], name($node),
    $node/@* ! utils:atty(.) => string-join("")
  )
};
 
declare function utils:build-path(
  $nodes as node()*
) as xs:string* {
  distinct-values(
    $nodes//* ! fold-left(ancestor-or-self::*, '', utils:pathing(?, ?))
  )
};
```

and is called from an XQuery by:
```

xquery version "3.1";

import module namespace utils = "http://canofbees.org/ns/xquery/utilities";

```

I have this particular module installed in my $BASEX/repo directory - more on that in the packaging link from earlier.

Hope that's more helpful :) (and closer to the mark!)

Best,

Bridger
