Interesting...
Devils' advocate: as far as I can tell, the symbol itself determines what sets
of attributes are valid. This is a problem: suppose a backend wants to
provide a set of alternatives for a default library symbol like
resistor-1.sym?
The more serious problem is that such an approach (without a file-format bump)
will not allow alternatives to have different pinouts -- but this is one of
the main objects of the exercise!
