Thank you Jos!
Observing, and to some extent fearing, the nature of the recent datatypes
discussion, I was wondering if we could bring some more structure to it by
asking for a test case. Then I saw this message from Jos and thought this
might be the basis of a test case we could decide on. Is it? Is there an
entailment test here?

ps: Someone (Jos?) has a badly formed email address configured for Patrick
- my email server barfs when I try to reply.
"Patrick Stickler <patrick.stickler" <patrick.stickler@nokia.com>
should be
"Patrick Stickler" <patrick.stickler@nokia.com>
Oh and similarly for PatH and RDFCore for that matter.
