I am not into that kind of modelling, so just a few general comments from
me:
- Do we really want to go with csymbol? From your document, I understand
that it might be to keep compatibility with CellML 1.0 and 1.1? If so, then
I really don't see why you would want that, since most (all?) of the
existing CellML-capable software are unable to deal with uncertainty. So, it
might just be better (cleaner) to use 'proper' element names?
- Why "uncert1" (as opposed to, say, "uncert" or something that doesn't
have a "1" in it) in the csymbol definition URL?
- Regarding your two examples, it would help the reader if you were to
mathematically introduce them rather than just provide the corresponding
CellML code.
- Regarding the CellML code you give as an example, it might help to put
the units definitions before the component definition. Also, it would be
good to respect the indentation (especially for the math element), and use a
smaller font or reduce the margins, if necessary.
