Yes, agreed.

OK, if I understand your point, you are saying that it
should be acceptable to have kinetic laws with sboTerms but
without math filled-in?

It seems to me this would put us in the situation (I think
it was Ralph Gauges who pointed this out) that it would
cause all software to be required to understand sboTerms,
simply because models containing only sboTerm and no math
would now be considered valid.

I think allowing sboTerms on Reaction would be a fine idea.

Hmm. I think if one used user-defined functions, the
substitution problem would be avoided.

I thought I had already posted the whitepaper on this, but
apparently not (or I can't find it now). It must have
gotten wrapped up in the stochastic/discrete vs continuous/
deterministic proposal we were discussing off-line last
year. Argh. Well, let me just claim for now that I think
there are ways of reducing the symbol-correspondence burden.
