Section 6.1 says:

Note that the "Addr Length", "ipv6-address(es)", and "Service 
Parameters (SvcParams)" fields are not present if the ADN-only mode 
is used (Section 3.1.6).

It should say:

Note that the "Addr Length", "ipv6-address(es)", "SvcParams 
Length", and "Service Parameters (SvcParams)" fields are not 
present if the ADN-only mode is used (Section 3.1.6).

Notes:

The paragraph is presumably copied from section 4.1 (DHCPv6 Encrypted DNS Option), and omits the "SvcParams Length" field, which is only present in the IPv6 RA Encrypted DNS Option. Mandating the presence of a superfluous length field when using the ADN-only mode seems like an oversight.
