It seems to me that it is *never* appropriate to guess at media-types or 
semantics by picking apart URIs in a computer program.  It is entirely 
fair and often desirable to use the design of URIs to convey information 
about the hierarchical structure of an information space, and to provide 
a suggestion to the human reader about what might be there. -Tim
