Dear Coleagues:

I have only a question about the "merging dictionaries" part. It is essential
when creating a virtual dictionary that validates a given CIF the order in
which the (real) dictionaries or fragments are concatenated and the form in 
which name collisions are resolved. However although each CIF would include the 
pointers to those dictionaries which should be used to validate it, there is no 
way of indicating how these dictionaries have to be concatenated. In the 
examples, dictionaries are merged and data files are validated by external 
programs (cifdiccreate and dictcheck) that require some human intervention. 
However validation of data files through virtual dictionaries could be an 
automated task and therefore at least the mode of solving name collisions should
appear also within the data file (assuming, for instance, APPEND for the 
dictionaries listed in the _audit_conform_ loop). Should some appropriate
items be included in the core?

After clarifying this point I would approve the document.
