  Thank you for confirming this.

  I’m not questioning that (although we could have a discussion about
what “in situ” means); I was only asking about the details of how the
LPPL is supposed to be interpreted in this case.  As you know, I’ve had
to answer similar questions in the past, so I’m always interested in the
opportunity to clarify the issue.
