The documentation for the TLS package:

http://golang.org/pkg/crypto/tls/

and the comment at the top of tls.go:

https://github.com/tav/go/blob/master/src/pkg/crypto/tls/tls.go

both say:

"Package tls partially implements the TLS 1.1 protocol, as specified in RFC
4346."

However, from looking at the code, it appears it implements SSL 3.0 and TLS 1.0 for
servers, and only implements TLS 1.0 for clients.  It does not appear to implement TLS
1.1.

Specifically, in common.go, it says:

    minVersion = versionSSL30
    maxVersion = versionTLS10

It appears that this min and max are used by the server, via the mutualVersion function.
 The client has the additional constraint that the version be at least TLS 1.0, and
since the max is also TLS 1.0, the client only supports TLS 1.0.

It would be nice if TLS 1.1 (and even 1.2) was supported, but until then, the
documentation should accurately reflect the versions currently supported.  Also, it
would be nice to expand upon what is meant by "partially implements".  Are
there known ways in which the implementation does not conform to the SSL 3.0 and TLS 1.0
specifications?  Are there known interoperability problems with other TLS
implementations?
