This article is probably one of the worst and most boring articles on XML ever. It lists non-patterns (in one case, an anti-pattern) that are completely useless and either fail to address the problem they set out to or address a problem that doesn't really exist. Don't waste your time reading it. Oh, and it also has fun disparaging Perl perfectly gratuitously en passant.
Is it just me or is xml.com increasingly becoming a waste of otherwise perfectly good bytes?
