Yes, and this has been available since 1999 with XSLT 1.0.  I have 
linked from my web site to a conference paper titled "Simple 
Worldwide Aggregation Using XSLT":

  http://www.CraneSoftwrights.com/#reading

It describes how companies licensing our training material maintain a 
private XML web page on their web sites with information regarding 
their deliveries of our courses.  Every Monday I run an XSLT 1.0 
stylesheet that goes around the world aggregating the information 
from those pages into our schedule page.  They don't have to tell me 
they've changed any information, they just update the private page.

And the 1.0 stylesheets implement a fall-back when the connection to 
the web page fails (though this scheme involves using an extension to 
write the last successfully-retrieved page to a local file).

Companies that have distributed sources of information could do the 
same thing:  each group maintains their own XML fragment with their 
own information at a reserved web address and the aggregation pulls 
it all together when needed.

I hope this is helpful.
