On the contrary, I don't think there is a more appropriate place to spell 
out this distinction than in the specification.  GRDDL suggests an 
alternative route that is more robust for sure, but the GRDDL 
mechanism only accounts for *one* particular goal in transforming content.

XSLT can be used (in very similar fashion) to generate other artifacts 
(from the same source document) for very different ends and I think you do 
more harm than good in not spelling out this distinction *especially* when 
you consider how ubiquitous support for xml processing PIs is within 

What I'm suggesting isn't so much a justification of not 
using PIs but rather being clear about how the GRDDL mechanisms relates to 
similar transformation mechanisms to give an appropriate context for 
(web client) implementors who will undoubtably have to reconcile this

I'm not suggesting accomodating PIs within GRDDL, but giving the 
appropriate context for implementors who have will have to contend with 
the various, automated ways XML content will be processed within their 
architecture - PI's being the most prominent example.
