What about using the file: protocol for pages over a local network or off 
a CD-ROM?

(CDs with HTML and various multimedia objects are appealing to many
electronic publishers for obvious reasons: you can reach more people who
can use their own browsers to view the work rather than supply
proprietary viewers for a limited numbers of platforms and hope they
work on machines in the future...)

No. The user agent handles a specific type in a certain way. It is not 
always possible for the agent to know what type a file is (either because 
of the protocol or because of a misconfigured server). So using the TYPE 
attribute tells the agent to treat the resource as a certain type... it 
tells it what type it is, and the agent handles it as such. (It doesn't 
need to know the "correct" MIME type; it only needs to know a MIME type 
that allows it to handle the document in the way the author desires.)

It's not being discarded. But there are cases where the server should be 
overidden.
