No, we have not yet implemented SOAP 1.2 support in OpenSAML 2.x. It
will be in 3.x, but that doesn't help you.

That's not really correct.  You might be able to kludge it to get a SOAP
1.2 Envelope emitted via the 1.1 object providers, but it won't be
pretty, and it won't help for the received message, which OpenSAML won't
know about because it doesn't have any providers registered for those
QNames.

You can theoretically use the all-purpose XSAny provider, but that's not
much better, and I think you'll have problems trying to use the SOAP
client with that.

The really correct way is to just implement the 1.2 providers and
register them in your config.  There's only half a dozen or so.  That's
more complicated, but it's the correct way.  The developer's guide might
be helpful there:

But for the most part I think you can just copy the 1.1 classes and
change the namespaces and prefixes. I think you'll also have to subclass
or copy and change or reimplement the SOAP client and related classes,
since I think it assumes a SOAP 1.1 Envelope.
