Hi Andrew,

To simply delete reaction elements from a version 1.1.1 specification
seems the wrong approach to me. This means that while a 1.0 model is a
valid 1.1 model it could be an invalid 1.1.1 model. So the most minor
version change is the one that invalidates the model?!?

If anything, a version 1.1.1 could mark the reaction element as
deprecated but still valid. Although if I recall some other
specification developments correctly (i.e., docbook), an element needs
to be marked for deprecation a version before it is actually deprecated
and removed from the language. Not sure what process we want to follow
for CellML but this 1.1.1 draft specification would not be the way I
hope we go. Otherwise how can anyone have confidence in using CellML at
all when core elements can arbitrarily be dropped from the specification
with no notice?

Also, I'm wondering if we could set some ground rules for the
development of new versions of CellML. Rather than people simply
submitting draft specifications, I would favour an approach whereby
people submit proposals (using whatever technology we end up using) and
then we can discuss which version of CellML that proposal should be
considered for. This would allow us to start developing a detailed road
map of the features people want to include in new versions of CellML and
the priority with which they are incorporated, as well as possible
target dates for the various releases.
