I think using Booleans is 'cleaner' The

http://www.w3.org/TR/rdf-sparql-XMLres/

defines the return values for ASK as 'boolean'. Ie, I would prefer to say

<Test0086> rdf:type test:TestCase;
     dc:contributor "Ivan Herman";
     dc:title "NO triple for a non-reserved @rel value";
     test:informationResourceInput <0086.xhtml>;
     test:informationResourceResults <0086.sparql>;
     test:expectedResults "false"^^xsd:boolean;
     test:purpose "Test that NO triple should be generated for a 
non-reserved @rel value";
     test:reviewStatus test:approved;

with the understanding (to avoid lots of typing) that the default value 
for test:expectedResults is "true"^^xsd:boolean.
