Then you are requiring a schema. All sorts of application specific
optimizations can be made to the format and parser if you have a fixed
schema for the data you expect to consume. As Derek pointed out earlier,
most of the binary XML proposals out there all assume some sort of fixed
schema or pick some subset of XML to target. 

The interesting question is whether a general solution exists (e.g. a
solution that encompases both the use cases of XML Web Services and Web
site syndication using RSS 2.0) . 

It is impossible to make anything foolproof because fools are ingenious.
