    # We can't delete records using recordIdOpaque, since character
    # sets are handled differently here in extended services from how
    # they are used in the Alvis filter's record-parsing, and so
    # non-ASCII characters come out differently in the two contexts.
    # Instead, we must send a record whose contents indicate the ID of
    # that which we wish to delete.  There are two ways, both
    # unsatisfactory: we could either fetch the actual record them
    # resubmit it in the deletion request (which wastes a search and a
    # fetch) or we could build a record by hand from the parsed-out
    # components (which is error-prone and which I am not 100% certain
    # will work since the other contents of the record will be
    # different).  The former evil seems to be the lesser.
