Section 2.8 says:

    The output from the AEAD is twofold:

   o  A ciphertext of the same length as the plaintext.
   o  A 128-bit tag, which is the output of the Poly1305 function.

It should say:

    The output from the AEAD is the concatenation of:

   o  A ciphertext of the same length as the plaintext.
   o  A 128-bit tag, which is the output of the Poly1305 function.

Notes:

Section 2.1 of RFC 5116 defines the AEAD interface, and that interface produces a single output, C (or an error).
