Try TIFFClrFieldBit(tif, FIELD_DOCUMENTNAME), a macro defined in
tif_dir.h . Note: use FIELD_DOCUMENTNAME, not TIFFTAG_DOCUMENTNAME!
I've never used it, but it looks like it does what you want.
I don't think there currently is a public function for this, but I think
it would be a good idea to have one.
