True, so the property would need a way to automatically get numbered sequentially.

I don't understand how 'auto', 'avoid' and 'always' differ. (FYI: 'inherit' is 
now defined at the declaration syntax level and need not be mentioned in 
property definitions.)

I also don't understand what this property _does_. Does it make elements 
invisible? How? What order do elements reappear? etc.

There is a fatal flaw in the propsal I made, by the way: it has pseudo-classes 
that depend on properties. I'll need to think about it more.
