When using the inplace zonefile parsing support providing a zonefile that has a CHAOS or other class for an RR causes error expected rtype.

Even if this should not work for other reasons, the error should not be about an expected rtype.

If a class is unknown one might expect it to be treated as CLASS.

For example replacing IN in a SOA record with CHAOS causes this error.

Ah, user error. Using actual https://www.iana.org/assignments/dns-parameters/dns-parameters.xhtml#dns-parameters-2 CLASS mnemonics or any unsigned integer number works fine.

RFC 3597 style CLASS also works (as in does not cause a parsing error).

What doesn't work is an unknown mnemonic, which produces the expected rtype error.
