There isn't a new version of the COSINE schema.

But the attributes defined in RFC 1274, which were not added to RFC 4524 [1], are used in the usual DNS zone schema which defines object class 'dNSDomain2'. The DNS zone schema defines more attributes for DNS RRs and all of them have a SUBSTR matching rule defined.

If you reject this patch because you don't want to change a "standard" schema the other possibility would be to completely hunk out these RFC 1274 declarations from cosine.(schema|ldif) to avoid collision with separate DNS schema files adding them.
