-A compliant implementation MUST support the following algorithm combinations for the KEMRecipientInfo `kdf` and `wrap` fields when the corresponding Composite ML-KEM algorithm is listed in the KEMRecipientInfo `kem` field. The KDFs listed below align with the KDF used internally within the KEM combiner. An implementation MAY also support other key-derivation functions and other key-encryption algorithms within CMS KEMRecipientInfo.
