Well yes, but why can't you provide at least in the comment section
below the '---' a pointer to the latest version of this reference muck
and PKS global state if you can't explain at least the concept of the
two things here?

It's one thing that you anticipate something but a different thing
whether it's the right thing to do.

Thanks,
