It looks like the problem is not in the element itself but with the previous element that has no separate enclosing tag, only />.

The problem is not resolved, unfortunately - I just found the reason why it happens. I think it's related to the problem described for the similar .NET component here

https://forum.aspose.com/t/28050

When there is an empty/self-closing tag the next tag in XML is treated as a part of a previous one. In my case it's self-closed tag and then next tag which is considered as a part of .

The method that causes the problem is importAnnotationFromXfdf from PdfAnnotationEditor
