It ... sort ... of makes sense. I'm going to have to set aside the book 
on XSLT and take a really close look.

Or could you kindly highlight where in the schema you perform each one 
of these steps?

BTW, you don't seem to have split your schema into sub-schemas.

Inspired by your approach, it would be nice to have the varying elements 
share a common name but live in unique namespaces. For example the 
general version of the element Foo in the common namespace com and thus 
referenced as com:Foo, while the customized version of Foo be declared 
another namespace cus, and thus referenced as cus:Foo. The goal of 
course would be to find a way of identifying the appropriate Foo 
namespace in the top-level schema. Note that Foo may not appear in the 
top level schema, and is often deeply nested in other elements contained 
in the top level level schema.
