[xml] any built-in support for stylesheets in PI?

[Chris Ryland <cpr emsoftware com>]

If an document comes with a PI that defines the style sheet to be 
applied, is there any way to automate picking up the style sheet from 
the PI & applying it?

Or does one have to simply go through the document's PIs and find the 
right one, then do the usual xslt dance?

Cheers!
