At one level we can keep this simple and store the full signature in the dictionary; this will keep the schema the same but will mean that values from the latest release may be incompatible with older versions. Given that problem exists I am tempted to take this further and actually add the parameter mappings to the dictionary to avoid having to reparse the signature every time.
Anyway, both of these hit the problem Dan orginally raised about not having a process defined for changes to the physical database. I would like to open this thread to resolve that.
