And if I get one of your notation-encrusted documents, and don't have an
application that can cope with it, where do I find the information? I
can't. The problem isn't that MIME mechanisms are worse than notation
mechanisms - it's that there isn't a central and flexible registry for
either system that is publicly available and works.
I see notations as worsening this problem because they exist inside
documents and become management nightmares if the registry of whatever kind
changes. Allowing information to identify itself when requested avoids
this complication - the registry may not be any better, but at least I
don't have to modify my documents to match up to the registry.

Will the software that reads your documents still be running in a hundred
years, or will people be cracking open your archives with applications that
can't make head or tail of your notations?

Yes, but I don't recommend building country lanes as four-lane highways
with double guardrails either, especially in a world where guardrail
standards change frequently.

I don't. And I don't recommend them to others, either. Describe, yes, but
