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
preference.

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.

Hence

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.
