I was involved, in that I was already on the IETF-types mailing list at that time, while at the Computer Graphics Unit in Manchester. Alan wrote it, I believe the UK Advisory Group on Computer Graphics (AGOCG) was the body that determined the registration was needed, and I read and commented on the draft before it was finalised.

Yes, I was.

Ouch, interesting. At the time of the original registration, ISO was clearly seen as the only source of such standards.

It seems that a small update to the MIME registration would be useful and would not impact existing implementations, but wold legalise current practice.

I don't know how much work that is or wether it will help, but am interested to hear from those who have more experience with that aspect.

Are things like PIPs and so on ISPs?
