#39 Allow to re-run action for a result document.

[Edwin Dankert]

It would be nice if it was possible to re-run an
action, like validation for only one result documents.

The use-case is that we would like to make sure that
all xml documents of a set are valid.

This results in a number of valid documents and some
invalid documents.

It would now be nice to be able to edit one of the
invalid documents and select the document in the list
and re-run the validation for this specific document only.
