After my form.Form validates the user input values I pass them to a separate (external) process for further processing. This external process can potentially find further errors in the values.

Is there a way to inject these errors into the already validated form so they can be displayed via the usual form error display methods? Or, are there better alternative approaches?

One suggestions was to include the external processing in the form validation. I'm not crazy about this since the external process does a lot more than just validate.
