I received an email recently that had a text attachment with this XML stuff in it:
It didn’t look familiar, so I did a few Google searches, and eventually found RFC 1896: The text/enriched MIME Content-type. It isn’t XML: it’s an SGML-influenced syntax for simple enrichments to plain text emails. Funny that it’s been out there for so long and I’d never run across it before.
This feels like an abandoned line of development in the progress of technology, like gopher, Archie, and Veronica. They were good ideas, but something even better, and at first blush not even that different, came along and blew them away.
BTW: Zvon’s great RFC Repository is still the best way I’ve found to read RFC’s, but they seem to have sprouted an unusually diverse bunch of ad mushrooms. They seem to be sprinkled everywhere, in remarkable variety, and for some very spam-worthy products. Too bad, but necessary I suppose.
