I think the only way you can make this work and still retain the cascade 
philosophy is if you require includes and link elements, through which 
variables propagate outwards to have an explicit qualifier to request this.

That way any stylesheet can re=define a variable without caring whether 
the name is already in used, and have the scope of that variable limited 
to itself, or the sheets it includes, but still have the option of 
defining a global set of variables.

This is not perfect, because it only really allows one set of variables 
to propagate sideways at any level, e.g. you can't have a set of 
corporate variables and a conflicting set of variables for one 
department, contributing multiple sheets, then have another (matrix 
management?) department having following style sheets, but which use the 
corporate variables.


 From the comments being made about corporate rules and the involvement 
of Apple, I think this is being introduced for a market that considers 
the cascade a nuisance, because that market believes in central control 
of presentation.
