The formal model was an effort after-the-fact to describe W3C XML Schema,
not something that was done from the start.
I frequently share your aversion to altars to formality, but have to admit
that formal models are a really powerful foundation for pattern-matching
applications. RELAX NG and regular expressions demonstrate that quite nicely.
Do they do everything? No, but it's sometimes nice to know the foundation
isn't a hodgepodge of ill-fitting ideas.
