Is the problem that there is <> around the URI in
  <http://www.wikidata.org/entity/Q111> Point(351.83 -14.47)
Otherwise this is in the lexical space for geo:wktLiteral.

Although the spec for geo:wktLiteral says that the lexical space consists of
an optional URI followed by a geometric value, the examples in the spec
enclose the URIs in <>.  I would expect that implementations of geo:wktLiteral
would thus allow enclosing <>.
