  * UIDNA API implements the IDNA protocol as defined in the IDNA draft 
- * (http://www.ietf.org/internet-drafts/draft-ietf-idn-idna-14.txt).
+ * (http://www.ietf.org/rfc/rfc3490.txt).
  * The draft defines 2 operations: ToASCII and ToUnicode. Domain labels 
  * containing non-ASCII code points are required to be processed by
  * ToASCII operation before passing it to resolver libraries. Domain names
  * that are obtained from resolver libraries are required to be processed by
  * ToUnicode operation before displaying the domain name to the user.
  * IDNA requires that implementations process input strings with Nameprep
- * (http://www.ietf.org/internet-drafts/draft-ietf-idn-nameprep-11.txt), 
+ * (http://www.ietf.org/rfc/rfc3491.txt), 
  * which is a profile of Stringprep (http://www.ietf.org/rfc/rfc3454.txt), 
- * and then with Punycode (http://www.ietf.org/internet-drafts/draft-ietf-idn-punycode-03.txt). 
+ * and then with Punycode (http://www.ietf.org/rfc/rfc3492.txt). 
  * Implementations of IDNA MUST fully implement Nameprep and Punycode; 
  * neither Nameprep nor Punycode are optional.
  * The input and output of ToASCII and ToUnicode operations are Unicode
