Somewhat related to this issue, I have implemented in xarray-simlab some logic to validate xarray.Variable objects (dimensions, dtype, etc.). See this base class and some sub-classes here. I use that in a way which is quite similar to pandas-validator(i.e., using class attributes).

I'm currently in the process of refactoring this using attrs, which supports both validator functions and type annotations. Not sure how to use the latter for xarray objects, though (BTW I wasn't aware of python/typing#513, good to know!!).

I agree that it would be nice to have a more generic way to describe xarray objects that can be reused in many contexts.
