Dear TLS group,

I think it is the intent of RFC 5246 that a TLS server, in addition to
tolerating an "extensions" field in the ClientHello that is nonempty as
a whole, MUST ignore individual extensions that it does not recognize.
However, I cannot find this stated anywhere in RFC 5246.  Am I missing
something?  Would this be worthy of an erratum?

Thanks,
Matt
