This hasn't been done before, so validation plugin support needs to be
added to JOSM core. Any help is appreciated, but you can also implement
your test as if it was a core validation test. Open a ticket on trac and
attach the patch and we will add the necessary hooks.

As low level alternative you can register an upload listener. This is
already possible at the moment - intercept the upload and show a custom
dialog. However, this does not integrate with the normal validation process.
