ComputeCapability would be better as an open enumeration if you expect software to be able to use it as a selection key.

Hi Stephen

The ComputeCapability in the AcceleratorEnvironment is an attribute strongly recommended for Nvidia GPUs descriptions:
https://en.wikipedia.org/wiki/CUDA#GPUs_supported
It's not properly a version number, we may say that is a "category number" or "category ID", it can't be an enumeration.
We discussed a lot in the past about that attribute but it seems to me that we still don't have a clear idea.

BTW, since the list of comments for that attribute is getting very long I reset it and put a short description.
