I'm kind of glad to hear that since I had similar discomfort with it myself. I
thought it might be the least worst option though so I figured I would say it
out loud.
Perhaps something like
Operator Class
and
Data Type Class
Data type classes happens to involve operator classes but it sounds like
you're looking for them to specify other behaviours of how data types
inter-relate than just their operator classes anyways.

(Actually that's a bit of an odd case since real-world folders aren't
generally nestable and actually many early operating systems didn't allow them
to be nested either. We're just so used to the computer metaphor that we
forget what it's originally supposed to represent.)
