Long time ago I remember reading some wip paper or something that loftar was planning to write for university or something about how everyone insisting that pretty much everything that could be should be in xml(or was it something else) is silly because it's rarely the best way to store data and that just making your own thing that actually suits whatever you are doing better requires just writing an interpreter which shouldn't be that hard for most programmers to do.
Anyway I tried to look that up since my memory of it has gotten somewhat fuzzy but I'm having trouble finding the link to it, can anyone link me to it?
