I think that "global semantics" might mean something less here than you
imagine. As an example, consider <Price>. What is meant by global
semantics in this context is only what a <Price> element is -- that is,
it is a price in money of an object, and it may always be in a
particular currency or it may have an attribute denoting the currency.
This is very different from what the price applies to, which is
obviously context dependent.

These kinds kinds of semantics are quite wide-spread and allow you to do
basic processing with context-insensitive routines before passing the
result on to a context-sensitive routine.
