Race/RaceType >= 'R' is true for the <RaceType>S</RaceType> element, 
Race/RaceType <= 'R' is true for the <RaceType>H</RaceType>.
So the result you see is a consequence of >= or <= applied to node-set 
operands (in XPath 1.0) or sequence operands (in XPath 2.0) being true 
if there is at least one item in each operand node-set/sequence for 
which the comparison is true.
