[6:30:31 AM] Eric Prud'hommeaux: @ivoka, alasdair and i were working through negation expressions.
<S_1> { !dc:created xsd:date } # dc:created xsd:date: reject, dc:created xsd:time ???
<S_2> { dc:created !xsd:date } # dc:created xsd:date: reject, dc:created xsd:time reject
<S_3> { dc:created xsd:date {0} } # dc:created xsd:date: reject, dc:created xsd:time reject
<SE1> EXTRA dc:created { !dc:created xsd:date } # dc:created xsd:date: reject, dc:created xsd:time ??? (maybe more likely to accept?)
<SE2> EXTRA dc:created { dc:created !xsd:date } # dc:created xsd:date: reject, dc:created xsd:time accept
<SE3> EXTRA dc:created { dc:created xsd:date {0} } # dc:created xsd:date: reject, dc:created xsd:time accept
(Re: <S_1>, <SE1>, He's using the ShExDemo, which still has this negation. This is not defined in current ShEx

[6:39:16 AM] Eric Prud'hommeaux: ultimately, i can't remember how `predicate !type` (with a simple type) differs from `predicate type{0}`
[6:39:51 AM] Eric Prud'hommeaux: i know you thought a lot about this so i'm hoping to take advantage of that
