The outstanding issue from Oct 2 is B below

I discussed this with Peter in Florida and we have a joint proposal on B.2
and I would be happy to abstain on a resolution for B.1 following Peter's
(see below)

B.2 datatypes

Peter agreed with my analysis that this is an error in S&AS, and that test
I5.8-016 should be correct.


PROPOSE that S&AS be modified to require a triple <xxx> rdf:type
rdfs:Datatype . in OWL DL for any user defined datatype <xxx>, even when
only used inside a typed literal.

This is no change to test and small change to S&AS.

B.1 uris as annotations

While we still disagree on this one, I am happy to concede - unless other WG
members feel strongly about this.
If someone else wishes to propose along the lines
Modify resolution of Issue 5.26 OWL DL Syntax, so that uris used only as the
obejct of annotation properties do not need to have a type triple.

This would be no change in S&AS and small change to test.

I would abstain.
