Sure, I appreciate the problem you have encountered with dual parameter spaces. Not sure what to do about it, at our end we will move to global parameters.

I agree in general. But I don't think this is really the case for parameters. This is definitively not reciprocal, but a local param can always be transformed in a global one. *This* transformation is a tool problem. Again, my main problem in current SBML is the coexistence of local and global parameters in the *same* file, and the associated problems (such as a local parameter able to overide a species or a compartment). And I am really happy of any discussion dealing with parameter problem. Their frequency is IMHO the surest sign that the current situation is not satisfactory.
