This is very wrong. The Punycode encoded value does not include the "xn--" string.

The text should instead read:
       Internationalized domain names MUST be converted using
       the  steps in section 4 of [RFC3490] using the ToASCII
       function.

Agreed.

Calling this an ACE label which is identified by the "xn--" prefix may avoid some of the confusion.

This could also be written as:

 Internationalized domain names MUST be converted using the
 steps in section 4 of [RFC3490] into "ACE" labels using the
 ToASCII function.
