> 3.  The encoded three byte CBOR byte string containing 0x42_4F_52.

This is in: https://datatracker.ietf.org/doc/html/draft-ietf-cbor-file-magic-07.txt#appendix-C
I see the argument to make this an appendix since it does not tag CBOR
content.  I fear that the reviewers and IESG will be confused though.

Should it really use CBOR as bytes 8-11, since the content is not, in fact, CBOR?
Maybe we should say something else.  I don't feel strongly about this.
