From 5.8.1:

"When declaring an atomic step, the subpipeline in the declaration must be empty. And, conversely, if the subpipeline in a declaration is empty, the declaration must be for an atomic step."

Does this mean that this:

<p:pipeline name="new-identity"> <p:identity /> </p:pipeline>

is technically declaring a compound step, and not an atomic step? And if so, is it impossible to declare an atomic step that's not an extension implemented at the processor level (if that makes sense)?

Thanks,
