I think even with such a best practice specification the model 
repository still needs to handle the case where there are multiple 
primary references - a CellML representation of a model coupling 
separate mechanics and electrophysiology models together would be an 
obvious example.

As for more detailed citations, in the work I am doing I end up with 
specific variables, components and equations referenced to different 
articles. So in a CellML 1.1 model hierarchy there are many different 
combinations of "primary" references possible depending on the 
particular sub-models pulled into a specific experiment. The base model 
has one primary reference but then I am adding various extra features to 
the model which all have their own primary reference or making changes 
to parameter values for various experiments etc.

I don't think the bio_entity or math_problem would be appropriate in 
these instances.
