Precisely what I have been saying.... (though I would say "interpreter 
rather than "observer").

In compilers, you usually (not always, usually)  go from 
source->AST->object tree with something doing the conversion from 
AST->object. XML is the same. The XML core DOM is roughly an AST... 
and we interpret that as we wish. Even humans go through the phase of 
parsing into "elements" then determining their "type" .

The magic is is in the interpreter, not the data.
