I would like if it could be possible to add a version attribute
we have the rhea release version,
we have the rhea reaction identifier
we should have the reaction version number.
each time a change is made on a specific reaction, the rhea reaction identifier should be keep, but the version attribute should be increase by one.

change should be link to at least equation (metabolite chebi reference and stoichiometry) and potentially to crossreferences

the goal is when data are imported in other application, we could quickly know if the reaction has chgnaged or not.
and so if we need to update our internal reaction.

Thanks for your help.
