In twinql (either AllegroGraph 2.2.5 or the unreleased 3.0) this
produces three empty results:
<?xml version="1.0"?>
<sparql xmlns="http://www.w3.org/2005/sparql-results#">
<head>
</head>
<results>
<result>
</result>
<result>
</result>
<result>
</result>
</results>
</sparql>
Sounds like a bug in someone's software.
