Section 4.3 says:

dmr-prefix6-len: 8 bits long; expresses the bitmask length of the 
IPv6 prefix specified in the dmr-ipv6-prefix field.  Allowed
values range from 0 to 128.

It should say:

dmr-prefix6-len: 8 bits long; expresses the bitmask length of the 
IPv6 prefix specified in the dmr-ipv6-prefix field.  Allowed
values range from 0 to 96.

Notes:

This field is used to provision the default mapping rule prefix length, which is defined in section 5.1 of RFC7599:
The DMR IPv6 prefix length SHOULD be 64 bits long by default and in any case MUST NOT exceed 96 bits.
