Back in 2003, Meg Hourihan was writing the now-defunct Kinja.com, and
wrote a rant about OPML's failing DTD (OPML having been designed by
the same developer as RSS2, as you know), rant that I think applies
just as well to RSS' lacking DTD, or from there extends (heh, get it?
xml? extends?) to just about any badly documented XML format, and how
developers tend to understand the way they work as they see fit to
their own purposes.

I think "discrepancy" is the word I'm looking for here, but then again
