To state what I suspect is a common question:

Do we know the current availability of Saxon 9.4? i.e. inclusion with which version of Oxygen (or other tools of choice) . . ?

If the answer is in the nature of 'widely available', I would vote for choice #1

Ok world,

Here's the deal: I want to make XML Calabash work with Saxon 9.4. And
I'm sure I can. But some of the underlying Saxon APIs have changed, so
if I do, then it won't work with Saxon 9.3 anymore.

1. I can just announce that as of some version, Saxon 9.4 is required.

2. Or I can go to the trouble of providing abstractions around the
   changed APIs and adapting to whatever version of Saxon is present.

Choice 1 is easy easy for me, impossible for you with Saxon 9.3.

Choice 2 is hard for me and will eventually have to be ripped out as
I'm sure that sooner or later I'll write new code that uses 9.4 APIs
and I'm not likely to be willing (or possibly even able) to back-port
those changes to 9.3.

So, if choice 1 is hugely inconvenient for you, now would be the time
to say something.
