AnswerBook2, which is at docs.sun.com, takes exactly the steps, in 
claim 1, though not using XSL (DynaText stylesheets). It uses DynaWeb, 
and has been used in *exactly* this manner since 1994. Every other 
claim was also *demonstrated* in DynaWeb in 1994 or 1995. The use of 
XSL was also developed and demonstrated in about 1998/1999 or so, 
though it was a trivial variation of existing systems.

I have proof of this both in documentation that I wrote, code that I 
wrote, documentation that was released, and PR material (presentations 
etc.) that were released. In fact,  there is already a patent on this 
kind of thing, though (mistakenly, ask Steve & Chris) my name is not 
on one of them.

  US6055544 Generation of chunks of a long document for an 
                      electronic book system
  US6167409  Computer system and method for customizing context
                      information sent with document fragments across
                      a computer network

Interesting that they don't site the prior art that exists *within 
Sun*, and that was used before that at many places, including Novell. 
If you broaden the notion of "request", even more prior art exists.

Sheesh. People should at least look at history before claiming it for 
their own.
