You are allowed to do SASL authentication if <mechanisms
xmlns='urn:ietf:params:xml:ns:xmpp-sasl'/> has been advertized by the
server.
After SASL authentication has been done, the stream gets reestablished
by sending a stream header and new stream features.
All servers I know will not include the above stream feature again if
authentication has already been done. Therefore with current
implementations you are not able to do multiple SASL-negotiations on the
same connection.
