> Microsoft might not be totally crazy for basing their docx file format on XML. Honestly, I'd expect them to be uniquely qualified by years of hindsight, shame, and regret to design a document format.

I don't know if unparallelled failure is a good indicator of design ability...

It's amusing though, pretty much the only area where the article actually claims XML doesn't kill babies is in representing trees. Ehm, how about sexprs for hierarchial data representation?

My personal opinion is that XML always kills the baby, and nothing I've experienced has made me reconsider that assessment.
