+    OpenMP operations that can wrap a single loop nest. When taking a wrapper
+    role, these operations must only contain a single region with a single block
+    in which there's a single operation and a terminator. That nested operation
+    must be another loop wrapper or an `omp.loop_nest`.

This description needs updating. It should say that this is for OpenMP operations that can represent a single leaf of a composite OpenMP construct. It would also be good to use that description to update this PR's description, so it's easier for reviewers to understand what this change is for.
