I'm not so worried about that but there is one critical fix I require:

2.5

REMOVE
  http://ilrt.org/discovery/2001/07/rdf-syntax-grammar/#section-Namespace
reference and cite the correct corresponding syntax WD section:
  http://www.w3.org/TR/rdf-syntax-grammar/#section-Namespace

DELETE
 [[check this]]

The warning in red may be removed, since that is in the cited
section, and expanded in the latest draft.

This link was actually in published in the WD last time even though I
asked it to be removed last time.

Changed I'd like to see, not requirements:

I'd suggest removing the RDFS namespace [[where??]], the RDF vocab
document serves as that definition.


I've also just noticed (was 3.4) now 4.1 defining an rdf triple
has changed terminology again:

 [[
An RDF triple describes an arc in an RDF graph. It contains three components:
   *  a subject node
   * an predicate, labelling the arc, which is a URI reference, and
   * an object node
 ]] -- http://www.w3.org/TR/rdf-concepts/#xtocid103646

now

[[
An RDF triple contains three components, called:
    * the subject
    * the predicate, which is an RDF URI reference
    * the object
]] -- http://sealpc09.cnuce.cnr.it/jeremy/RDF-concepts/2002-11-05/rdf-concepts.html#xtocid103646


I've been using the terms "subject node" and "object node" since they
are more distinctive than "subject" and "object" and shorter
than "the subject of the triple".

I'd prefer to to see this retained if that doesn't cause you
problems.

Finally, I'd love to see all the definitions and uses of terms linked
- everywhere "RDF triple" etc. is used linked to it's definition and
so on for all the terms.  Should be a global search / replace mostly.
