Do you have a proper reference for the normal-diff format?  Are you  
legally allowed to document it yourself in an Internet-Draft?  If  
not, it might be difficult in practice to register a MIME type for  
the normal-diff algorithm.  Part of the IETF's attempt to generally  
protect software developers from the position of having to implement  
a standard requiring technology they're not allowed to use.
