So, GRDDL would be defining a specific, fine-grained parsing mechanism
independent of the *inevitable* development of a general-purpose XML
Processing Model which answers the question (among others) of "What will
the impact of a default processing model be on existing XML documents
and processors,...?" --

How can this be independent of #issue-faithful-infoset (which has been
closed, re-opened, closed, and postponed - taking XProc's charter into
account)?

Would the notion of minimum processing not need to be defined very
explicitly (in the absence of any current definition)?
