[CSS3 Line] line-stacking-ruby property definition

In Ruby module, property 'line-stacking-ruby' referenced as a way to control whether Ruby text is taken into account for calculating line box. However, in current WG Line module draft I have access to this and some other properties marked as old and to be removed.

So, Paul (as editor of Ruby module) and David (as editor of line module), which spec is correct?

    - is this property considered not necessary and reference should be removed from Ruby module, or
    - is this property now become one of the values of 'line-box-contain' property and, again, Ruby module should be edited accordingly

And on general note, what are the plans for making these modules public?

Thanks,
Sergey
