I am increasingly taken by an approach that specifies which grammar rules
are not used.

I have just implemented this in the jena2 RDF/XML-ABBREV writer, which
permits the following rules to be switched off:

http://www.w3.org/TR/rdf-syntax-grammar/#parseTypeLiteralPropertyElt
http://www.w3.org/TR/rdf-syntax-grammar/#parseTypeResourcePropertyElt
http://www.w3.org/TR/rdf-syntax-grammar/#parseTypeCollectionPropertyElt
http://www.w3.org/TR/rdf-syntax-grammar/#propertyAttr
http://www.w3.org/TR/rdf-syntax-grammar/#idAttr
http://www.w3.org/TR/rdf-syntax-grammar/#section-List-Expand
http://www.w3.org/TR/rdf-syntax-grammar/#section-Reification

(bagID has never been supported by any writer).

Other rules that can, plausibly, be switched off are:

http://www.w3.org/TR/rdf-syntax-grammar/#resourcePropertyElt
http://www.w3.org/TR/rdf-syntax-grammar/#resourceAttr
and
nodeID within property elements.
However, I have not implemented these.

Switching a rule off means that the output conforms with the revised syntax
with that section deleted.

This code will ship later this week or early next week in J2P2 (announcement
on jena-dev@yahoogroups.com), it is currently available by anonymous CVS
from http://sourceforge.net/projectes/jena
