I was about to report this as a bug before I realized it is connected with a preference setting. Running oXygen 13.0, with expanded Java memory settings, the following query returns a complete result: element out { for $i at $pos in 1 to 2000000 return <el>{$pos}</el> } but this query truncates after 600K results: for $i at $pos in 1 to 2000000 return <el>{$pos}</el> The truncation depends on the Preference setting for XQuery - "Size limit of Sequence view (MB)". That is understandable. However, it would be a help to the user if there was something more than just a "Transformation successful" message. For example, an error diagnostic saying "Memory limit 2 MB - results truncated", maybe with a link to the preference setting where you can increase the limit.
