STRUCT_REF_SEQ_DIF could use the token _struct_ref_seq_dif.db_seq_num
to specify the sequence position at which a point difference occurs
in terms of the sequence of the referenced database.  While this can
be inferred by very careful use of _struct_ref_seq.db_align... tokens,
that is clumsy and error-prone when there are insertions or deletions.
