add warnings for private-use subtags (those of the form "x-")

Aryeh suggested it might be advisable to warn users about documents that contain private-use subtags. I tend to agree that it would be worthwhile.
I've had this open for a while but seems I'm not likely to be working on it any time soon, so moving to "fixed"; can be revisited/reopened later
