## OK: then it complains about more than one value:
#:foo :value "2"^^xsd:integer; :value "1"^^xsd:integer.
#:foo :value "2"^^xsd:decimal; :value "1"^^xsd:decimal.
#next two cases: does not complain and returns three (or one) values:
:foo :value "2"^^xsd:decimal; :value "1.0"^^xsd:decimal.
:foo :value "2"^^xsd:decimal; :value "2.3"^^xsd:decimal.
:foo :value "2.3E13"^^xsd:decimal.
