 /**
 23  
  *  Converts its argument to a boolean value, using a modification of the rules
 24  
  *  for Schema instances: true is represented by the literal values "true" or
 25  
  *  1, ignoring case, while false is everything else. This is very different
 26  
  *  from the XPath function <code>boolean()</code>, in which any non-zero value
 27  
  *  or non-empty string/nodeset is true.
 28  
  *  <p>
 29  
  *  Note: the name of this class is <code>XsiBoolean</code>, but it's name in
 30  
  *  an XPath expression is "<code>boolean</code>". This is to prevent name
 31  
  *  collision with <code>java.lang.Boolean</code>.
