how to flag entries with serious problems

     In the PDB format document there is a new record type
specified that has not yet been implemented.  It would seem
useful to have an equivalent in an mmCIF but I could not find
any in the dictionary.  Here are the relevant parts of the PDB
decsription:

CAVEAT warns of severe errors in an entry. Use caution when
working with this entry.

COLUMNS        DATA TYPE       FIELD          DEFINITION
1 - 6          Record name     "CAVEAT"
9 - 10         Continuation    continuation   Allows concatenation of
                                              multiple records
12 - 15        IDcode          idCode         PDB ID code of this entry
20 - 70        String          comment        Free text giving the
                                              reason for the CAVEAT

PDB will add this record to incorrect entries that are not withdrawn
from the set of released entries. This record will be used sparingly,
and only after an external review has been made.

CAVEAT will be added by the PDB to entries known to be incorrect.

Example:

         1         2         3         4         5         6         7

CAVEAT     1ABC    THE CRYSTAL TRANSFORMATION IS IN ERROR BUT IS
CAVEAT   2 1ABC    UNCORRECTABLE AT THIS TIME
