No Validation Result when xml document is not well formed

When validating an XML document that is not well formed, the Schematron validation is not performed. In this case no validation status is affected to the object (null in DB). This causes the validation status to be "NOT AVAILABLE" in validation report and empty in log list (see screenshots).
When xml is not well formed, the validation status could be set to "NOT PERFORMED" as it is indeed not done for not well formed documents.
Several possibilities to solve the problem :
- Affect "NOT PERFORMED" status when the file isn't well formed
- Change log list and validation report pages to better interpret null values (not very compliant as null values may appear in other situations + change code in many places)
- Add a default value to the validation status field (eg "NOT PERFORMED")
