for example, here's some examples of data structures from the spec 
expressed in CDDL:

attestationObject expressed in CDDL:

attestationObject = {
  "fmt":        tstr,
  "authnDat":   bytes,
  "attStmt":    bytes
}

all attestation stmts expressed in CDDL:

PackedAttestationStatement = {
  "alg":        tstr,
  "sig":        bytes,
  "x5c":        [ attstnCert: bytes,  * bytes ],
  "daaKey":     bytes,
}


TpmAttestationStatement = {
  "ver":        tstr,
  "x5c":        [ attstnCert: bytes,  * bytes ],
  "alg":        tstr,
  "sig":        bytes,
  "certInfo":   bytes,
  "pubArea":    bytes,
}


AndroidKeyAttestationStatement = {
  bytes
}

AndroidSafetyNetAttestationStatement = {
  "ver":        tstr,
  "response":   bytes,
}


FidoU2fAttestationStatement = {
  "x5c":        bytes,
  "sig":        bytes,
}
