     Shalom,
     
     I think they would have the same rules for appearing in
     source as the `timescale (not in a module, just outside).
     I'm not sure what else needs to be defined...
     
     Actually, I would want to define some standard attributes
     for this purpose in 1364 (1364.1 was the first to introduce
     standard attributes, but this would be a good place for them).
     I wouldn't think we'd want to let them be used everywhere,
     but having attributes to specify the version for modules,
     configs and for config_rule_statement would be pretty helpful.
     Tools already have to have compatibility modes... this just
     gives a standard way to get at them. Note that we would have
     to define the location of attributes in the bnf for configs.
     
     Stefen
