Simple way to set a ref-value by xquery-result

Hi,
me again.

At least i don't know if there is a simpler way, but i hope so.
Actually my way to do this might be:

1. Send Submission that query the db and writes back the results into an
instance.
2 Set Value of another instance with the query-result.

Is there a way to do something like:
<xforms:setvalue ref="xxforms:instance('control-instance')/max-nr"
value="{call an xquery and return the result here}" />
So that i only need one line without calling an extra Submission? I
think a read about an xforms:call-xpl - would that be a proper way?

Regards, Marcus

Yes, you can call a pipeline from an XPath expression with the
xxforms:call-xpl() function. If that pipeline handles the call to
eXist then that will work. It is not necessarily less work though.
