That isn't what the spec says. The spec currently says "here are the 
possibilities" (or "here are the constraints", if we take your suggested 
change), and then says whether various linking mechanisms are constrained 
when they use those possibilities (or whether those constraints apply to 
those elements).

If an item can be in states A, B, and C, and the spec says that A is 
allowed and B is not allowed and doesn't mention C, then there is a 
problem. That's the situation the spec is in right now.

The spec currently isn't defined in those terms. If it was, there would 
not be an issue.
