Apache uses bar.html.fr vs. bar.html.de, etc - in other words, configured 
a particular way, everything after the first . is considered a metadata 
keyword which maps to a namespace containing content-type, language, and 
encoding keywords.  Thus, index.html.en and index.en.html would denote 
the same fact that this file is an English HTML file.  Obviously this is 
not scalable - each of those dimensions should have its own namespace.  
So, we start the long and perilous journey into the metadata swamp.... 
something like GN/WN's .menu files, where the metadata is laid out 
explicitly and what's in the file name isn't important, is closer to what 
the right approach might be.

But, these are all implementation details and largely irrelevant to HTML 
and HTTP protocols.  Defining a standard for this is important when one 
considers cross-server portability important, which I do.  Our work 
environment has to be focused on portability, because it simply isn't 
acceptible for us to force a client to use a particular server.   On the 
other hand, is defining a convention for server-side data structure too 
much like reinventing CORBA?
