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>. | |
