These are good points, and if this can be done, I would very much like
the golden parser to generate a warning when the timing reference load
is not specified. I get too many model without the load information,
making them nearly useless for timing verification. Most IBIS authors
leave them out, because they don't know what the parameters are, and
the specification makes them optional (interpreted as "not needed").
