Hi Markus,

The standard specification just shows examples for topics like “days”
and “books” with map constructors based on literal data.

If you are looking for functions to construct maps dynamically, maybe map:merge & map:entry are what you are after?

map:merge(

  for $i at $pos in 1 to 10

  return map:entry($i, $i*$i)

)

Best

Michael

I got informed that the data structure “map” got a clear meaning according to
XQuery programming interfaces.

I came along another clarification desire according to the mentioned standard
data structure.

The standard specification just shows examples for topics like “days”
and “books” with map constructors based on literal data.
How would the XQuery code look like if a detailed FLWOR expression would
be applied instead?

The subsequent CSV result output should show finally that keys and associated
values were properly determined before.
