Section 3.6.1 says:
k= Key type (plain-text; OPTIONAL, default is "rsa"). Signers and Verifiers MUST support the "rsa" key type. The "rsa" key type indicates that an ASN.1 DER-encoded [ITU-X660-1997] RSAPublicKey (see [RFC3447], Sections 3.1 and A.1.1) is being used in the "p=" tag. (Note: the "p=" tag further encodes the value using the base64 algorithm.) Unrecognized key types MUST be ignored. and in Section 9.1: [ITU-X660-1997] "Information Technology - ASN.1 encoding rules: Specification of Basic Encoding Rules (BER), Canonical Encoding Rules (CER) and Distinguished Encoding Rules (DER)", 1997.
It should say:
Both instances of "[ITU-X660-1997]" should be "[ITU-X690-1997]"
This is just a typo: "660" should be "690". The text of the reference is correct, but the document number is wrong.
