XMPP stream compression after resource binding

Hi all!

I'm trying to use XMPP stream compression (XEP-0138) with latest Smack API. Problem is it's not compliant with XEP-0170, that is order of stream features negotiation. XEP says:

• TLS
• SASL
• Stream compression
• Resource binding
• [Session estabilishing]

While Smack does:

• TLS
• SASL
• Resource binding
• [Session estabilishing]
• Stream compression

I know it might work with some XMPP servers, but I need to know if it's 100% safe to do that.

Thanks
