There is an example of a certificate signed with Ed25519 in that
document. As noted in the text:

  "The same algorithm identifiers are used for identifying a public key,
   identifying a private key and identifying a signature (for the two
   EdDSA related OIDs). "

Note, these OIDS are for EdDSA in pure mode so there is no hash, and
hence no need for a separate OID for the sig/hash pair.
