Is it possible to set the 'from' attribute for stream?

Is it possible to set the ‘from’ attribute for stream?

According to RFC 6120 it’s possible to set the ‘from’ attribute for stream https://tools.ietf.org/html/rfc6120#section-4.7.1

I didn’t find a way how to do it with smack 4.1

We need this for the ‘see-other-host’ implementation

Sending ‘from’ allows server to send to client ‘see-other-host’ request without SSL handshake and authentication which will speed up negotiation of connection, reduce network traffic and reduce resource usage on server side

Should be set if the username is configured: Smack/XMPPTCPConnection.java at 4.1 · igniterealtime/Smack · GitHub
