The think about notations as opposed to MIME types is that notations are a more general mechanism, not tied to any particular use domain, while MIME types are designed specifically to make things work smoothly on the Internet. Nothing wrong with that, but I just prefer the more general solution as a rule (but I'm like that). Because MIME types can be associated with notations (say by using the MIME type as the public or system identifier for the notation), the two mechanisms can be complimentary. Ideally, XML and SGML would have a mechanism for declaring specialized forms of notations, which would better reflect the way we use notations in the HyTime standard, for example. In HyTime, we defined several distinct types of notations: queries, storage managers, etc. It would be nice to be able to do something like: <!-- Declare a notation type: --> <!DCNTYPE -- Data content notation type declaration -- QUERY PUBLIC "this is the pointer to the authoritative definition of this type of notation" > <!-- Now use the notation type to declare a specific notation: --> <!QUERY SDQL PUBLIC "ISO/IEC 10179//NOTATION Standard Document Query Language//EN" > The "<!QUERY" declaration is still just a notation declaration, but it is more clearly specialized. I don't know if the value of this type of specialization is worth the cost, but it seems like a reasonable thing to do, in the abscense of any deep thought about the issue.
