I'm confused - perhaps we are using different words for the same thing. 
"Rendering usually starts after parsing". Which common UAs exhibit that 
behavour? If my connection is a POTS modem and I request a 100MB 
document, must I wait for the download to complete before I see 
anything? I would consider that a serious flaw. I'm prepared to wait for 
the stylesheet to fully load before rendering begins, but no longer.

I stand by my original point, which is that the original example 
(xml-stylesheet processing instruction referring to a fragment of the 
current document) is incorrect. It is incorrect because it _lies_ to the 
UA, asserting the existence of a stylesheet that cannot be proven to 
exist, something a rational UA will not tolerate.
