regarding comment: GRDDL should be usable in a messaging pipeline

I think the goal of the comment
http://lists.w3.org/Archives/Public/public-grddl-comments/2007AprJun/0069.html

is worthwhile.

This motivated:

the subsection entitled "The base IRI in a processing pipeline" in
http://www.w3.org/2001/sw/grddl-wg/base
(see quote below)

I would hope that the comment can be positively addressed with very few 
changes - merely a clarification that an information resource may 
include a resource that has not been accessed from the Web, plus the 
text quoted to give practical guidance.

[[
The base IRI in a processing pipeline
=====================================

A GRDDL aware agent computes GRDDL results when

     given a URI I of an information resource IR, and an XPath node N 
for a representation of IR

To use a GRDDL aware agent in a processing pipeline, as well as the 
XPath node N, it is also necessary to specify a corresponding IRI I. 
This is used as the base IRI when the other mechanisms do not apply. 
This corresponds to section 5.1.4 of RFC 3986. It is even possible for 
the default IRI used to bear no relationship with the XPath node N, but 
in such a case, we read:

     As this definition is necessarily application-dependent, failing to 
define a base URI by using one of the other methods may result in the 
same content being interpreted differently by different types of 
applications.

     A sender of a representation containing relative references is 
responsible for ensuring that a base URI for those references can be 
established.
