Hmm, that is odd. If the google.com domain doesn't exist, it should
reply with a stream level <host-unknown/> error. If is does, and isn't
willing to service, there are a few options, like sending
<policy-violation/>, <see-other-host/>, <host-gone/> or even
<undefined-condition/>. Otherwise the following applies.

One of the rules in section 6.1 of RFC 3920 states:

    If the receiving entity is capable of SASL negotiation, it MUST
    advertise one or more authentication mechanisms within a
    <mechanisms/> element qualified by the
    'urn:ietf:params:xml:ns:xmpp-sasl' namespace in reply to the opening
    stream tag received from the initiating entity (if the opening
    stream tag included the 'version' attribute set to a value of at
    least "1.0"). 

The phrase 'is capable of SASL negotiation' means supporting SASL and
showing this by returning a version >= 1.0 in the stream header. The
phrase 'one or more' means sending an empty <mechanisms/> element is an
error, and this should be reflected in the schema, where this
is not specified. Let's take this into account for 3920bis.
