Just looking through the code, I see we are aiming at Async API 2.6.0. I don't think 3.0 adds a huge amount to the schema, I'd have to have a look over the changes, but thought I'd check in to see if this is something we want to do?

We could add an addition that allows for selecting a version and generate the schema on that, i.e. Version 2, Version 3 on generate to output the appropriate schema.

Just thought dumping.
