Note that this test also returns false if the FieldA attribute is 0,
which may or may not be desired. To test whether the numeric value of
the FieldA attribute is NaN, you can alternatively use:

  <xsl:if test="number(@FieldA) = number(@FieldA)">
    ...
  </xsl:if>

This works because NaN is the only number for which $num = $num is
false.
