Silvia,

The preamble at  http://tools.ietf.org/rfc/  states -

"Obsoletes xxxx refers to other RFCs that this one replaces;
Obsoleted by xxxx refers to RFCs that have replaced this one."

https://datatracker.ietf.org/doc/rfc2327/  states that -

"Obsoleted by RFC 4566 <https://datatracker.ietf.org/doc/rfc4566/>
Updated by RFC 3266 "
<https://datatracker.ietf.org/doc/rfc3266/>

So 2327 has been replaced by 4566.

But if you look at  *http://www.ietf.org/rfc/rfc2327.txt*  you do not see
that it has been 'replaced' by 4566.
