Use the Qexo-specific write-to function:

Generate text nodes or string atomic values.
For example:

let $nl := "
"
for $i in (1, 2, 3) return
(<a></a>, $nl)

> what about indentation/tabs? so instead of:

If the structure of the quey matches the output (which is
the usual case) you can add string values or text nodes.
Here is a workin example:

declare xmlspace preserve;
for $x in (1,2) return
(<a num="$x">{
  for $y in (1,2) return ("
  ",<b num="{$y}">{
      for $z in (1,2) return ("
    ",<c num="{$z}">
    </c>)}"
  </b>)}
</a>,"
")

This allows you to fine-tune the output.
The xmlspace declaration is option; read the spec to
what it does.  The current Qexo implementation isn't
quite according to spec in that it sometimes fails to
insert a space between string values.  No big deal;
just a warning to expect some minor changes in future
versions.

Kawa also includes a pretty-printer that can add
automatic indentation.  I need to provide a way to
allow you to control that.
