Notation *declarations* exist within documents, but all they do is bind a local name to the universal name of the notation, like external parsed entity decls and namespace decls. Notation *definitions* are global, like the IANA MIME-type registry, but they piggyback on the URL system. > and become management nightmares if the registry of whatever kind > changes.

I should add one point to my potted summary: The binding of (universal) MIME type names to their specifications isn't allowed to change, except possibly for allowing upward-compatible extensions, like new characters in Unicode; for new semantics, new names (possibly via parameters) must be introduced. Overall, then, neither notations nor MIME types are subsets of the other; each has special properties the other lacks.

MIME type names are also implementation- and system-independent, though IANA is more de facto than ISO. Local renderers for them are not, of course. -- John Cowan http://www.ccil.org/~cowan cowan@c... You tollerday donsk? N. You tolkatiff scowegian? Nn. You spigotty anglease? Nnn. You phonio saxo?
