I would prefer such a solution. Why? The generic answer is that I would 
like to name my files myself, and, less generally---as we see in this 
case, the extension of a file does not always tell the language used to 
produce the file, e.g., rdf files may be written in xml or in n3, which 
is not xml. I would like to specify different editing modes for the same 
file extension.

Thanks! This works just fine.
