The rule in XMPP is that if you receive XML qualified by a namespace you 
don't undrestand, you ignore it. So either of these would be just fine:

<starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'>
   <dirk xmlns='http://tzi.de/'/>
</starttls>

<proceed xmlns='urn:ietf:params:xml:ns:xmpp-tls'>
   <psa xmlns='https://stpeter.im'/>
</proceed>
