That all seems reasonable to me, just one comment:

- At the moment, CellML doesn't explicitly support the rem element
(remainder function in MathML), even though CellML does allow its use (at
the risk of ending in a situation where a model may work fine in a given
CellML tool -- that supports the rem element --, but not in a nother -- that
doesn't support the rem element --). Now, say that we officially want CellML
to 'support' the rem element, how do we go about doing that?

Otherwise, Matt wrote:

Treat that model in what way? Surely, if a model uses some 1.2 elements,
then there must be a reason to it. Therefore, a 1.2 model cannot be treated
as a 1.1 model, or did I miss something?
