The -v option produces:
An error occured: System.ArgumentException: The XmlReader passed in to construct this XmlValidatingReaderImpl must be an instance of a System.Xml.XmlTextReader.Parameter name: reader
Do you have a fix for this?
I probably know that bug. Try to turn XInclude processing off using -xi option.
Validation and XInclude doen't play well. Just turn off XInclude using -xi option.
