Well, that's a problem, isn't it :-) ?  It _names_ a specific version,
but _points to_ the undated version.  If you take the name as
definitive, then it remains conformant.  If you take the pointer as
definitive, it could be seen as becoming non-conformant.

I say 'could be', because (and my colleague Michael Sperberg-McQueen
is the expert on this, I'll try to channel him on this), specs which
(name and) refer to undated versions should do so in a way which
allows implementations to track the resulting changes in an
implementation-defined way, that is, all they have to do to be
conformant is to identify which version they are (currently)
supporting.  That makes sense to me.
