Hi Pierre,

We should try to minimise the number of optional items and thus the  
variants a data group can have. Otherwise evaluating the file becomes  
really difficult since one has to check every time whether a certain piece  
of information is present or not. The decision whether a certain piece of  
data is present or not should happen at the level of the data groups.

Concerning the "particles" attribute: it does not hurt to store the  
information (just a few bytes), but one is in real trouble if one needs it  
and it is missing. And I think it is good practice to store some  
statistical information along with averaged data.
