... and now let us see the example of XSL, processing this 
document which will work in document() with 2 parameters 
but will be broken by resolving the URI in the way I was 
proposing ( silly me, I should resist discussing document(), 
because it was just N 4 in my list ).

I'm not saying that such a usecase does not exist ...
I don't see it yet... Maybe I don't understand you and 
the 'URI-sensitive'  usecase  is already here?

Macroprocessing takes place before XML 'processing'
has started. The transformation is provided with the 'top-level'
URI. Knowledge of 'top-level' XML URI is more than enough 
for real life. ( I think I already said that, I'm very sorry 
if it is still not clear. I don't know how to say this better ).

Of course, there could be some usecase when it is not enough. 
This is a usecase which I was asking for. I'm guess the usecase 
is to do something sensitive to the "chapter1/main.xml" ???

( In the future let us call the snippet you wrote above be ... 
book.xml ).

Let us reveal the usecase which has forced document() to have 
2 parameters ( when only one parameter + resolving document() 
not from 'XSL' but from 'XML' is really needed for 99% of cases ).
