SOAP 1.1 Vs. SOAP 1.2

I'm looking at SOAP and note that there is versions 1.1 and 1.2.

I was wondering what the list's opinions were on which version to adopt.

Has the world universally migrated to 1.2 or has it stayed with 1.1?

Is it best for a client to generate requests in (say) 1.1 and a server to 
expect to receive requests in either 1.1 or 1.2?

Should you try 1.2 and then fallback to 1.1 on some error condition?

The SOAP spec may cover some of this, but I was wondering what the reality 
was on the ground, rather than what the spec writers hoped would happen!

Thanks,
