[Standards] Question about stream features in xep 206

[Fabio Forno]

Example 2 in xep 206 shows the initial feature offers of the stream. I'm 
wondering if it's correct to show also <bind/> and </session> features, 
since before authentication they aren't available yet.

<stream:features>
    <mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
      <mechanism>DIGEST-MD5</mechanism>
      <mechanism>PLAIN</mechanism>
    </mechanisms>
    <bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'/>
    <session xmlns='urn:ietf:params:xml:ns:xmpp-session'/>
</stream:features>
bye,
FF
