Many years late, but I found this which actually worked for me. (From https://msdn.microsoft.com/en-us/library/office/bb497334.aspx)

(wordDoc is a WordprocessingDocument)

using DocumentFormat.OpenXml.Validation;

        try
        {
            var validator = new OpenXmlValidator();
            var count = 0;
            foreach (var error in validator.Validate(wordDoc))
            {
                count++;
                Console.WriteLine("Error " + count);
                Console.WriteLine("Description: " + error.Description);
                Console.WriteLine("ErrorType: " + error.ErrorType);
                Console.WriteLine("Node: " + error.Node);
                Console.WriteLine("Path: " + error.Path.XPath);
                Console.WriteLine("Part: " + error.Part.Uri);
                Console.WriteLine("-------------------------------------------");
            }

            Console.WriteLine("count={0}", count);
        }

        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
