Re: SBML survey: should consistency ofunitsbe required?

Dear Sven and all,
On the other hand I think the main benefit of units is that if units are known we can write tools that convert units, which is _needed_ for model merging. And this is only really possible if the units are correct. (And correct units are possible even for all these difficult cases involving mass units).
I don't know the background for the model merging efforts, but do all models need to be "mergable"? If not, then requiring units be consistent (in ALL models) so that models can be merged seems unnecessary.
If we do not require this (SHOULD) we should add a flag to the model to indicate if the units are to be considered consistent, so that a tool can know if operations working with units are possible. (This is necessary because
there are cases when a tool cannot find out if the units are
consistent or not)
If there are cases when a tool cannot find out if the units are consistent, then how is it possible to enforce consistency (i.e. SHOULD)?
