/**
 * DOM operations only raise exceptions in "exceptional" circumstances, i.e.,
 * when an operation is impossible to perform (either for logical reasons,
 * because data is lost, or because the implementation has become unstable).
 * In general, DOM methods return specific error values in ordinary
 * processing situations, such as out-of-bound errors when using
 * <code>DOMNodeList</code>.
 * <p>Implementations should raise other exceptions under other circumstances.
 * For example, implementations should raise an implementation-dependent
 * exception if a <code>null</code> argument is passed.
 * <p>Some languages and object systems do not support the concept of
 * exceptions. For such systems, error conditions may be indicated using
 * native error reporting mechanisms. For some bindings, for example,
 * methods may return error codes similar to those listed in the
 * corresponding method descriptions.
 * <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
