PJ Fanning commented on XMLBEANS-579:
-------------------------------------
[~a.pinske] XMLBeans is 20 years old. This has probably been the behaviour for
most of the 20 years. I'm afraid we can't change behaviour without affecting
existing users. XMLBeans is very much in maintenance mode and we are not
looking to make major changes.
If you can prove this is a recent regression, we would consider fixing it then.

> URL: https://issues.apache.org/jira/browse/XMLBEANS-579
> Project: XMLBeans
> Issue Type: Bug
> Affects Versions: Version 5.0.1
> Reporter: Alexander Pinske
> Priority: Major
>
> When generating a sample, usually the top-level-element is xml-fragment. But
> when the type contains only one child-element, it becomes the root.
