[O] Private flag or property

[Karl Voit]

Hi!

I am still in the process of converting (lots!) of old data into
Org-mode format.

I stumbled over a private-flag PalmOS datebook used to maintain.

Is there a *common* way of expressing a private flag/property yet?

Or is there no pseudo-standard and I should stick to my «:PRIVATE:
True» property I am thinking of? (Is there a necessity for the
«True» string in my example (property without value)?
