 This extension is a future-proof and portable solution that supports these two
 requirements. Instead of using a fixed set of kernel enqueue arguments, the
-approach is to introduce the `exp_launch_property_t` type that enables a more

-Each `exp_launch_property_t` instance corresponds to a specific kernel launch

-Only one new function is introduced: `urEnqueueKernelLaunchCustomExp`.

 Many kernel lauch properties can be supported, such as cooperative kernel
 launches. As such, eventually this extension should be able to replace the
