If more values are possible in the future, then we should also define how to
react to an unknown value.

From a compatibility point of view, it would be better for an newer
application to add a new attribute, and tell the old applications how to
interpret this by adding the old attribute until all apps are updated.

Summary:
- use visiblilty=visible|hidden
- missing visibility ==> visible
- unknown value      ==> visible

If nobody objects, let's just do it that way. We can still make a forward
compatible extension with that, if anyone else cares.

I think so, because it doesn't affect how the image looks.  Would be nice if
the saved ORA would preserve the value, I guess.
