This is a copy of current check in secretDefineXML...
The secret->def->private is our stored one and def->private is the new
one. As I'm reading it, it looks right; however, going with the
suggestion means one could not change either way (e.g. public->private
or private->public). Then again maybe I'm reading your comment wrong.
FWIW: I've changed the name later to "isprivate" to make it clearer (and
to avoid that potential magic word private).

Oh right - relic of intermediate edits where goto label didn't exist
Thanks for sticking with this so far -
